I am male and age is 31 years old. Six months back may be in gym lifting light weight next day I got severe pain in biceps. I taken the tablets for inflammation. Now two months back I was doing push ups and next day I got the same pain in biceps in my another hand. I taken the tablets. Now I was not doing exercise at all therefore I did some squats for my lower body. So Now when I sit like squat in toilet I feel pain in my one leg for 10 seconds. Thereafter I does not feel anything. I met physiotherapist and even other doctors they told its very normal in gym. But my legs and hands are working fine but when I stretch my hands backward I feel pain in lower biceps. I really don't understand why it happened in both the biceps at a interval time. Secondly why it is taking so much time in repairing because I am not able to go gym. I just checked in yahoo in a article for vitamin b12. Thereafter I went for blood test and the result was 139 PG/ml and normal is 174 -878. So my question is 1) is my vit b 12 is low and it is effecting my injuries ? 2) I am vegetarian so it may happen that I lack other nutrients ? 3) I am exercising but I do not get the result . So is it vit b 12. 4) What is the reason behind injuries of hand and legs 5) Why injuries takes lot of time in repairing.
