I have peripheral sensory loss and now I feel it's increasing I was ok when I was in 9th class . Both of my feet gradually started bending inwards and now there is a non healing wound on my toe since 7-8 years . I took several medications since then but no positive response is there. Now I feel little bit of numbness in my fingers of my hand . They easily get burn with small heat and blisters are formed easily. There is severe pain in back with long standing and I do not gain weight. There is family history of TB No history of diabetes hypertension syphilis AIDS I tried everywhere I want to know the diagnosis why is it happening what's the reason behind it It suddenly starts to happen
