Hello dear,
The symptoms as mentioned in your post can be attributed to compression of blood vessels & nerves in the finger.
Investigations like X ray of the hand & Doppler study will be helpful in clinching the diagnosis.
However, other causes for the symptoms need to be ruled out, such as:
1. Any fluctuation in blood pressure levels
2. Altered blood sugar levels
3. Inadequate hydration & nutrition status.
4. Deficiency of certain nutrients like Iron, Vitamin B 12, Calcium,
Magnesium, etc.
Till then, management involves:
1. Nervigenic agents (like Vit B6, B12,
Folic acid) as well as
multivitamin & mineral supplementation.
2. Maintain adequate hydration & nutrition status, take proper rest and avoid stress.
If symptoms still persist, kindly
consult a Neurologist for a proper clinical examination including
nerve conduction study.
Wishing your friend a Good Health.
Take care.
