Here is a thorough but practical breakdown for your mom's situation:

Left-Sided Low Back Pain with Muscle Spasms - What You Need to Know

Most Likely Causes (in order of probability)

Based on the presentation - left-sided, non-radiating, spasmodic - these are the top candidates:

1. Acute Muscle Strain / Paravertebral Muscle Spasm The single most common cause. The muscles alongside the spine (erector spinae, quadratus lumborum) go into spasm from overexertion, awkward posture, or minor strain. Tenderness on pressing the left paraspinal region is usually present. This is the #1 cause of acute LBP in general practice. - Bradley and Daroff's Neurology, p. 1100

2. Lumbar Facet Joint Syndrome Found in up to 35% of LBP patients. The pain is typically unilateral (can be left-sided), worsens with back extension and lateral rotation toward the painful side, and does NOT radiate below the knee. Physical exam shows paraspinal tenderness. - Bradley and Daroff's Neurology, p. 1100

3. Sacroiliac (SI) Joint Syndrome Causes pain on one side of the low back, sometimes radiating to the hip or thigh (but not down the leg). It gets worse going upstairs. Tenderness directly over the SI joint. The Patrick test can reproduce the pain. - Bradley and Daroff's Neurology, p. 1100

4. Left Kidney Issue (Important to Rule Out) Left-sided back pain that is colicky/spasmodic in nature should raise the possibility of:

Kidney stone (renal calculus) - classically a crampy, "coming-and-going" pain at the flank/costovertebral angle
Urinary tract infection or pyelonephritis - pain at the left flank + possibly fever, burning urination
Goldman-Cecil Medicine specifically notes: "Genitourinary disorders can cause colicky pain referred to the flank and costovertebral angle."

5. Other causes to consider depending on her age/history:

Degenerative osteoarthritis of the lumbar spine
Fibromyalgia (if pain is also present elsewhere)
Rarely: aortic pathology, diverticulitis, ovarian cyst/pathology (in women)

Red Flags - See a Doctor Promptly if ANY of These Are Present

Red Flag	What it May Mean
Fever, chills	Infection (kidney, disc)
Unintended weight loss	Malignancy
Pain worse lying down / at night	Tumor, infection
Urinary/stool problems, saddle numbness	Cauda equina - EMERGENCY
History of cancer	Metastasis
Pain after trauma (fall, accident)	Fracture
Age > 50 + new-onset severe pain	Osteoporotic fracture, AAA
Pain not improving after 6 weeks	Needs imaging

The absence of ALL red flags is 99% predictive of a non-serious cause. - Symptom to Diagnosis, 4th Ed., p. 137

What You Can Do at Home Right Now

Non-pharmacological (first-line, best evidence):

Heat application to the lower back - one of the most effective acute measures
Gentle activity as tolerated - strict bed rest actually makes it worse
Avoid heavy lifting or twisting for now
A firm but comfortable sleeping surface helps

Medications (short-term):

NSAIDs (ibuprofen, naproxen) - first-line; take with food to protect the stomach
- Note: paracetamol/acetaminophen is NOT effective for back pain per recent evidence
Muscle relaxants (e.g., cyclobenzaprine, tizanidine) - helpful for spasms, usually prescribed short-term (3-5 days)
Harrison's, 22nd Ed., p. management section

Follow up with treatment:

Physical therapy and core-strengthening exercises once the acute phase settles
Spinal manipulation (physiotherapist/chiropractor) has evidence for acute LBP

When to See a Doctor

If the pain doesn't improve in 2-3 days of home care
If there is any fever, burning with urination, or pain when the left flank area is tapped gently from behind - this could suggest kidney involvement and warrants urgent assessment
If pain worsens significantly or begins to radiate down the leg

For a simple muscle spasm without red flags, most people recover within 2-6 weeks with conservative care. Imaging (X-ray/MRI) is NOT needed upfront unless red flags are present. - Symptom to Diagnosis, 4th Ed.

One practical tip: Gently tap (with a fist) on the left back just below the ribs (the costovertebral angle). If this produces sharp pain, that points more toward kidney involvement rather than a pure muscle problem - worth telling a doctor.

Good - I now have the evidence needed. Here is a practical, age- and HTN-specific medication guide:

Medication Guide for Muscle Spasm Back Pain in a 55-yr-old with Hypertension

Important note: Hypertension changes the medication choices significantly. Please consult your doctor before starting, especially since NSAIDs interact with BP medications. The suggestions below reflect what is typically prescribed in this situation.

⚠️ The NSAID Problem in Hypertension

This is the key issue. NSAIDs (ibuprofen, diclofenac, naproxen) are normally first-line for back pain BUT:

They can raise BP by up to 14 mmHg in people who already have hypertension
They interfere with antihypertensive drugs - especially ACE inhibitors, ARBs, and diuretics (which are commonly used for HTN)
They increase kidney stress - which matters more in older patients with HTN
Firestein & Kelley's Textbook of Rheumatology - NSAIDs can attenuate the effects of antihypertensive agents including ACE inhibitors and beta-blockers

Recommended Drug Combination (Typical Prescription)

Option A - Preferred (Short-term, 3-5 days)

Drug	Dose	Timing	Purpose
Thiocolchicoside 4 mg OR Chlorzoxazone 250-500 mg	4 mg OR 250-500 mg	Twice or thrice daily	Muscle relaxant - targets the spasm directly
Paracetamol 500-650 mg	Up to 3x/day	After meals	Mild pain relief - safe in HTN
Pantoprazole 40 mg	Once daily (morning)	Before breakfast	Stomach protection (if any NSAID is added)

Why paracetamol over NSAIDs? Although paracetamol has modest analgesic effect alone, when combined with a muscle relaxant for a spasm, it is the safest choice in HTN since it does not raise BP or interfere with antihypertensives.

Option B - If Pain is More Significant (Use with Caution in HTN)

If the pain is not controlled by the above and the doctor agrees to a short NSAID course:

Drug	Preferred Choice	Why
Naproxen 250 mg twice daily (with food)	Safer among NSAIDs in HTN patients (better cardiovascular profile than diclofenac/ibuprofen)	Lower CV risk; use shortest course possible
+ PPI (Pantoprazole 40 mg)	Mandatory with NSAID	Stomach protection
+ Monitor BP daily	-	NSAIDs can spike BP

Firestein & Kelley's Rheumatology - "Naproxen + PPI/misoprostol" is specifically recommended when CV risk > GI risk

Avoid diclofenac in HTN patients - it has the worst cardiovascular profile among common NSAIDs.

Option C - For Sleep (Nighttime Pain/Spasm)

Tizanidine 2 mg at bedtime - a centrally acting muscle relaxant with mild sedation; helps with nocturnal spasms. Start low (2 mg) as it can cause dizziness. Also has mild BP-lowering effect (alpha-2 agonist) - actually somewhat beneficial in HTN.

Practical Prescription Summary (What a Doctor Would Typically Prescribe)

1. Thiocolchicoside 4 mg - twice daily x 5 days (after meals)
2. Paracetamol 500 mg - twice or thrice daily x 5 days (after meals)
3. Local diclofenac gel / Voltaren gel - apply to painful area twice daily
   (topical NSAID - minimal systemic absorption, safer for BP)
4. Heat pad to lower back for 20 min, 2-3x/day

Topical diclofenac gel is an excellent option here - it provides local anti-inflammatory effect at the muscle with very little systemic absorption, so it does NOT meaningfully raise BP. This is a practical workaround for the NSAID-HTN problem.

What to Avoid

Ibuprofen - raises BP significantly in hypertensive patients
Diclofenac oral (long-term) - worst CV profile among NSAIDs
Etoricoxib - raises BP more than other NSAIDs
Benzodiazepines (diazepam) as muscle relaxants - habit-forming, not appropriate for short home use

Don't Forget

Continue her BP medications as usual - do not skip them
Check BP at home once or twice while she's on any NSAID
Adequate hydration - drink enough water (helps kidneys and muscle recovery)
Short bed rest is okay but encourage gentle walking - prolonged bed rest worsens back pain
Usually improves in 3-5 days with the above

Disclaimer: These are general medical education guidelines. A doctor should review her specific antihypertensive medications before prescribing, as drug interactions depend on which BP drug she takes (ACE inhibitor, ARB, beta-blocker, calcium channel blocker, etc.).

Tell me final tablets. I am doctor

Understood. Clean prescription for acute lumbar muscle spasm in a 55F with HTN:

Rx — Acute Lumbar Muscle Spasm (HTN patient)

#	Drug	Dose	Frequency	Duration
1	Thiocolchicoside 4 mg	4 mg	BD	5 days
2	Paracetamol + Ibuprofen (Combiflam) — only if BP is currently controlled	1 tab	BD-TDS	3-5 days
3	Pantoprazole 40 mg	40 mg	OD (morning, empty stomach)	5 days
4	Diclofenac gel 1% (topical)	Apply locally	BD	5-7 days

If you want to avoid oral NSAID entirely (safer for HTN):

#	Drug	Dose	Frequency	Duration
1	Thiocolchicoside 4 mg	4 mg	BD	5 days
2	Paracetamol 650 mg	650 mg	TDS	5 days
3	Tizanidine 2 mg	2 mg	HS (bedtime)	3-5 days
4	Diclofenac gel 1% (topical)	Apply locally	BD	5-7 days

Clinical notes:

Thiocolchicoside is the backbone here - central + peripheral muscle relaxant, no BP effect
Tizanidine (α2 agonist) at 2 mg HS is actually mildly antihypertensive - net neutral or beneficial in HTN
Topical diclofenac gel gives local COX inhibition with negligible systemic absorption - no meaningful BP impact
Avoid oral diclofenac / etoricoxib - worst CV/BP profiles
Naproxen 250 mg BD + PPI is acceptable if oral NSAID is needed (naproxen has the most neutral CV profile among NSAIDs)
Monitor BP if any oral NSAID is used, even briefly
Heat + gentle mobilization alongside
