[|AI|]  Hi, There can be various reasons for numbness of your right hand. Definitely, it can be due to vitamin B12 deficiency (quite likely since you already have a history for the same). However, there are other reasons like cervical disc diseases (neck related problems), carpal or cubical tunnel diseases (local compression of the nerves) or tennis elbow (local damage to muscles and tendons). Even diabetes and thyroid related problems can also cause such symptoms. Since you also have problem with equilibrium then we need to look for ear and brain (infections and swelling) diseases also. Basically, we need to have a detailed evaluation to find the reason for the same. I feel first take care of your diet - good balanced diet, lots of fruits and vegetables. For non vegetarians' food like animal liver is good source of vitamin B12. In vegetarian diet also many cereals fortified with vitamin B12 are available. You can even start taking some multivitamins. If still the symptoms persist then you need to go for some investigations like complete blood count, vitamin B12 levels, TSH and sugar levels and if further required ENT check up and brain imaging (CT head). Take care. Hope I have answered your question. Let me know if I can assist you further.
