Hi Sri..
Thanks for contacting practo for health query.I am a senior physician Dr.Shanmugavadivu answering your health question.You have said you have nerves problem what sort it is?Is is a numbness or shock like pain or pricking pain.One thing I infer from your statement is you are underweight.First take
calcium rich food like milk,egg,butter,cheese and try to include red meat in your diet if you are a non -vegetarian for
B12 supplementation.Consult a doctor for opinion incase not getting better.
Hope this helps .
