Now I have excellent information. Let me compile a thorough, well-sourced answer.
Based on the medical textbooks and current evidence, here is a detailed explanation of what is likely happening with your mother:

What Is Likely Causing Your Mother's Symptoms

Your mother has three interconnected problems happening at the same time, all related to her diabetes and her medication. Here is a breakdown:

1. Diabetic Peripheral Neuropathy (Leg Pain)

This is the most common cause of leg pain in diabetic patients. High blood sugar over time damages the nerves, especially in the legs and feet first, then hands.
Symptoms include:
  • Burning, stabbing, or aching pain in the legs
  • Numbness or tingling
  • Symptoms often worse at night
  • Muscle weakness over time
This is called distal symmetric peripheral neuropathy - it starts in the feet/legs and gradually moves upward toward the hands and arms.
Goldman-Cecil Medicine confirms: "Painful diabetic neuropathy: Symmetric numbness and burning or stabbing pain in lower extremities."

2. Diabetic Cheiroarthropathy (Palm Stiffness / Difficulty Folding)

The difficulty folding her palm and finger stiffness has a specific medical name: Diabetic Cheiroarthropathy (also called "Diabetic Stiff Hand Syndrome" or "Limited Joint Mobility Syndrome"). This is a well-recognized complication of diabetes.
How it happens:
  • Chronic high blood sugar causes glycosylation (sugar molecules stick to collagen in tendons and skin)
  • This forms advanced glycation end products (AGEs) that cross-link with collagen, making it stiff and waxy
  • The skin on the back of the hand becomes thick and tight
  • The small joints (finger joints, wrist) lose mobility
Key sign: The "prayer sign" - the inability to press both palms flat together.
According to Firestein & Kelley's Textbook of Rheumatology:
"Prevalence between 45% to 76% of patients with type 2 DM have been reported, as well as an increase in frequency with age, disease duration, and poor glycemic control."
This condition affects 30-76% of diabetes patients with long-standing or poorly controlled diabetes. It can also involve carpal tunnel syndrome and trigger finger (locked/catching fingers), which are also more common in diabetics.

3. Vitamin B12 Deficiency (Very Likely - From Metformin)

This is a critically important finding for your mother. If she is taking metformin (the most common diabetes tablet), she is at high risk for Vitamin B12 deficiency.
Goldman-Cecil Medicine states clearly:
"Long-term use of metformin has been associated with vitamin B12 deficiency and worsening of symptoms of neuropathy, thereby suggesting that periodic testing of the vitamin B12 level should be performed in patients on long-term metformin therapy."
B12 deficiency makes nerve pain significantly worse. It causes:
  • Pain, tingling, and numbness in legs and arms
  • Weakness
  • Balance problems
  • Worsening of any existing neuropathy
This is very commonly missed in diabetic patients on metformin. Your mother should have her Vitamin B12 blood level checked urgently.

4. Other Vitamin Deficiencies to Consider

DeficiencySymptoms
Vitamin B12Leg/hand pain, tingling, numbness, weakness - worsened by metformin
Vitamin DBone and muscle aches, leg pain, generalized weakness
MagnesiumMuscle cramps, leg pain, stiffness
Folate (B9)Nerve symptoms, especially alongside B12 deficiency
Diabetic patients are commonly deficient in Vitamin D as well, since high blood sugar impairs its metabolism.

Regarding Telmisartan 40mg

Telmisartan (her blood pressure medication) does not directly cause these symptoms. However, poorly controlled hypertension reduces blood flow to nerves and muscles, which can worsen pain over time.

What Should Be Done Next

Please take your mother to her doctor and ask for the following tests:
  1. Vitamin B12 level (most urgent - especially if on metformin)
  2. Vitamin D (25-OH) level
  3. HbA1c (to check how well diabetes is controlled - the stiff hand syndrome is strongly linked to poor sugar control)
  4. Kidney function tests (urea, creatinine)
  5. Nerve conduction study (if neuropathy is suspected clinically)
  6. Folate/homocysteine levels
Practical steps:
  • If B12 is low, supplementation (oral or injection) often dramatically improves nerve pain
  • Better blood sugar control is the single most important thing to slow both the neuropathy and the hand stiffness
  • Physical therapy for the hand can preserve range of motion
  • Vitamin D supplements are generally safe and often helpful in diabetics with leg pain

Important note: This information is for educational purposes. Your mother must see her doctor for proper examination and blood tests. The hand stiffness and leg pain together in a diabetic patient need proper clinical evaluation to confirm the diagnosis and rule out other causes like thyroid problems, rheumatoid arthritis, or peripheral artery disease.

Give me some drugs to treat them

Here is a complete, textbook-backed guide to the medications used to treat your mother's conditions. All of these must be prescribed by her doctor - do not start any medication without medical supervision.

Drugs for Each Condition


A. For Leg Pain - Diabetic Peripheral Neuropathy

These are the standard drugs used, listed by priority:

First-Line (Most Recommended)

DrugClassDose RangeNotes
DuloxetineSNRI antidepressant30-120 mg/dayFDA-approved for diabetic neuropathy pain; first choice per most guidelines
PregabalinGabapentinoid150-600 mg/day (in 2-3 divided doses)FDA-approved; also improves sleep
GabapentinGabapentinoid300 mg at bedtime to start, up to 3600 mg/dayCheaper alternative to pregabalin; equal efficacy
Harrison's Principles of Internal Medicine (2025) states: "Symptomatic treatment using gabapentinoids (pregabalin, gabapentin), serotonin-norepinephrine reuptake inhibitors (duloxetine, venlafaxine)... have some efficacy for pain related to diabetic neuropathy."

Second-Line

DrugClassNotes
AmitriptylineTricyclic antidepressantLow dose (10-75 mg at night); effective but causes drowsiness; caution in elderly
VenlafaxineSNRIAlternative to duloxetine
Capsaicin 8% patchTopicalApplied to painful areas; reduces pain signals
Lidocaine patch (5%)TopicalGood for localized burning pain; no systemic side effects

Avoid as first choice

  • Opioids (tramadol, tapentadol) - only if nothing else works; risk of dependence

B. For Vitamin B12 Deficiency (Metformin-Related)

This is the most straightforward fix and can dramatically improve nerve pain.
TreatmentRouteDose
Cyanocobalamin (Vitamin B12)Injection (IM)1 mg daily for 1 week, then 1 mg/week for 4 weeks, then 1 mg/month for life
Methylcobalamin tabletsOral500-1500 mcg/day (commonly prescribed in India)
High-dose oral B12Oral1000-2000 mcg/day (if no severe deficiency or neurological involvement)
Per Washington Manual of Medical Therapeutics: "Initial treatment (1 mg/day IM cyanocobalamin) is typically administered in the setting of neurologic dysfunction."
Note: Methylcobalamin is the active form of B12 and is the preferred form for nerve-related symptoms. It is widely available in India as Mecobalamin (Mecobion, Methylcobal, Rejunex etc.).

C. For Stiff Hand / Diabetic Cheiroarthropathy

There is no specific drug that reverses this condition. The textbooks are clear:
"NSAIDs and steroid injections are not effective in management." - Firestein & Kelley's Textbook of Rheumatology
The main treatment approach is:
TreatmentDetails
Better blood sugar controlMost important - tight HbA1c control slows progression
Physical therapy / hand exercisesGentle stretching and mobilization to maintain range of motion
Analgesics for painParacetamol (acetaminophen) or low-dose NSAIDs for comfort only
Corticosteroid injectionIf trigger finger (locked finger) is present - local injection helps

D. For Vitamin D Deficiency (if confirmed on testing)

DrugDose
Cholecalciferol (Vitamin D3)60,000 IU once weekly for 8-12 weeks (loading dose), then 1000-2000 IU daily maintenance
CalcitriolIf kidney function is impaired (doctor must prescribe)

Summary - Quick Reference

ProblemFirst Drug of Choice
Leg nerve pain (neuropathy)Duloxetine or Pregabalin
B12 deficiency (metformin)Methylcobalamin (Mecobalamin) injection or tablet
Hand stiffness (cheiroarthropathy)Blood sugar control + physiotherapy
Vitamin D deficiencyVitamin D3 (Cholecalciferol)
General pain reliefParacetamol (safe in diabetics)

Important: Your mother is already on telmisartan and a diabetes medication. Before adding any new drug, her doctor must check for interactions and kidney function. Pregabalin and gabapentin can cause dizziness and falls in elderly patients, so they are started at low doses. Duloxetine can very slightly raise blood pressure, which matters given her hypertension. Always consult her physician before starting anything.

Can i give her tablets of neurobion forte

Neurobion Forte composition B vitamins diabetic neuropathy benefits safety

Yes, You Can Give Her Neurobion Forte - But With One Important Limitation

Short answer: Yes, it is safe and helpful as a starting supplement, but the B12 dose in it is too low to treat a significant deficiency.

What Is in Neurobion Forte (Indian tablet)?

VitaminAmount per tablet
Vitamin B1 (Thiamine)10 mg
Vitamin B2 (Riboflavin)10 mg
Vitamin B3 (Nicotinamide)45 mg
Vitamin B5 (Calcium Pantothenate)50 mg
Vitamin B6 (Pyridoxine)3 mg
Vitamin B12 (Cyanocobalamin)15 mcg

Why It Helps

All three key nerve vitamins - B1, B6, and B12 - are present. These are exactly the vitamins needed for:
  • Nerve repair and function
  • Reducing tingling, numbness, and burning pain in legs
  • Correcting the deficiency caused by long-term metformin use
It is safe, over-the-counter, affordable, and widely available in India. 1 tablet daily is the standard dose.

The Important Limitation - B12 Dose Is Too Low

This is the key point you need to know:
  • Neurobion Forte has only 15 mcg of B12 per tablet
  • For treating a genuine B12 deficiency (especially one causing nerve damage from metformin), doctors recommend 500-1500 mcg of Methylcobalamin per day
  • That means Neurobion Forte alone is not enough if she has significant B12 deficiency
What this means practically:
SituationWhat to do
B12 level not yet tested - mild symptomsNeurobion Forte daily is a reasonable start while awaiting blood tests
B12 level confirmed lowNeurobion Forte is NOT sufficient alone - she needs dedicated Methylcobalamin (Mecobalamin, Rejunex, Nervijen) 500-1500 mcg/day or B12 injections
Just for general nerve supportNeurobion Forte is fine

Better Alternatives Available in India

If her doctor confirms B12 deficiency, these are more effective:
BrandContainsWhy Better
Methylcobal / Mecobalamin 500 mcgMethylcobalamin (active B12)33x more B12 than Neurobion Forte
Rejunex CD3Methylcobalamin + Vitamin D3 + calciumCovers B12 and Vitamin D together
Nervijen PlusMethylcobalamin + Alpha lipoic acid + B6Good for diabetic neuropathy specifically
Neurobion Forte RF (injection)Methylcobalamin 1000 mcgFor severe deficiency - given by doctor

Bottom Line

  • Yes, give her Neurobion Forte - it is safe, has no interactions with telmisartan or her diabetes medicine, and will provide some benefit
  • 1 tablet daily after a meal is the standard dosage
  • Get her B12 blood level tested - if it comes back low, switch to a dedicated methylcobalamin supplement (500-1500 mcg/day) which is far more effective for nerve pain
  • Neurobion Forte is a good starting step but should not replace proper diagnosis and treatment of her underlying nerve condition
