Hi welcome to Health care magic forum. At the age of 25 years so much of numbness
means it is to be considered, it could be due to anaemia
, juvenile diabetis, or hypertension
I advise you to consult a physician for diagnosis and treatment, You may need to get c.t. scan of the neck, blood sugar, etc for conferermation of the disease,
Besides i advise you some diet recommendations as take more of green leafy vegetables, pulses, sprouts, fruits, juices, meat to provide iron and proteins
to the body.
Avoid taking potato, other tubers, tomato, cauli flower , coconut, egg, chicken, and sea foods as these may increase the numbness and pains of the joints.
Wishing for a quick recovery and thanks for calling.
