Sir, I am aged 31 yrs, working in Railways. I have been suffering from extreme body weakness for the past 9 years (from April 2014), which I don’t know why it happened to me. I was extremely confused the weakness happened. I was not able to do anything causally and some sort of inner pain was there always. Not able to tell whether it is muscle or bone pain. Immediately I took the vitamin - D test, it was low, but even after improving vitamin - D profile, the pain did not go. I could not go out easily in the sun, as I feel like fainting and the pain was always there. The pain has gradually reduced over the days, but not fully. I am really worried about my future, as to when this will end and can carry out normal activities. I am now easily struggling to carry out day-to-day activities easily and casually, so restrict my activities like going to work etc. and do not spend time on other things. During the start of this problem, my parents didn’t believe me and said I was bluffing. I somewhat moving my days with extreme difficulty, and really need help and I don’t know whom to consult for this problem. Kindly help me in this regard.
