Your symptoms could have a treatable physical cause, so do not dismiss them as anxiety alone.
Most relevant possibilities are:
  1. Hypothyroidism (underactive thyroid)
    Cold intolerance, anxiety or low mood, muscle cramps/aches, fatigue, constipation, dry skin, weight change, hair changes, and menstrual changes can occur. Cold intolerance and muscle cramps are both listed features of hypothyroidism in medical texts. A MedlinePlus thyroid overview also lists feeling unusually cold, weakness, muscle/joint pain, and dry skin.
  2. Raynaud phenomenon
    This is exaggerated spasm of the small blood vessels in response to cold or stress. It can run in families. It is more likely if the fingers become white or blue, numb, tingling, painful, and then red as they warm. MedlinePlus Genetics describes Raynaud phenomenon as cold- or stress-triggered episodes of narrowed finger blood vessels.
  3. Anemia, low iron, or electrolyte issues
    Anemia can cause feeling cold and fatigued. Low magnesium, potassium, calcium, dehydration, or some medicines can contribute to cramps. Cold intolerance is also associated with anemia and vascular problems in the MedlinePlus cold-intolerance review.
  4. Diabetes-related factors for your father
    Diabetes itself may contribute to circulation or nerve symptoms, particularly if it has been present for years or glucose control is poor. However, he should not assume diabetes explains it all. Thyroid disease, anemia, medication effects, and Raynaud-type symptoms should still be assessed.

What to arrange

Book a non-emergency appointment with a primary-care clinician for each affected family member, especially if this is persistent or worsening. Ask whether the following are appropriate:
  • TSH and free T4 for thyroid function
  • CBC and ferritin/iron studies for anemia or iron deficiency
  • Kidney function, glucose/HbA1c, and electrolytes including potassium, calcium, and magnesium
  • Medication review, especially in your father. Diuretics, some cholesterol medicines, and other drugs can contribute to cramps or cold symptoms.
  • Examination of pulses, skin temperature, sensation, and capillary refill
  • If hands change color in cold, evaluation for Raynaud phenomenon and, when indicated, related autoimmune conditions
Helpful preparation: note when episodes happen, whether one or both hands are affected, photos of any white-blue-red finger color changes, triggers, duration, cramps location, diet/hydration, medications/supplements, and associated symptoms such as constipation, fatigue, weight change, hair loss, or numbness.

Meanwhile

  • Dress in layers and use warm gloves in air-conditioned rooms.
  • Take regular movement breaks and gently warm hands rather than applying very hot heat.
  • Keep hydrated and eat regular balanced meals.
  • Avoid smoking/nicotine and excess caffeine, which can worsen vessel spasm and anxiety.
  • Do not start high-dose potassium, magnesium, iron, or thyroid products without testing and clinician advice.

Seek urgent care now if

  • One hand or foot becomes suddenly very painful, pale/blue, cold, weak, or numb and does not recover with warming
  • Chest pain, shortness of breath, fainting, severe weakness, confusion
  • Muscle cramps occur with severe weakness, palpitations, vomiting, or marked dehydration
  • Finger sores, ulcers, or black discoloration develop
A family tendency makes familial Raynaud susceptibility or shared thyroid/autoimmune risk possible, but testing is needed to distinguish these from anemia, nutritional/electrolyte problems, and other causes.
