male age 22.I used to over train my body muscles.Due to which my muscles have become very hard now overtime.Every time i exercise now,it becomes more hard.Just after 10mins of workout,my muscle group is as hard as rock.That s why i stopped going to gym.It has been more than 4 yrs dat i stopped workout.But i love bodybuilding even now,so some times i try lifting any random weights to check whether earthlings fine.But the muscles again become hard & it becomes nothing less than a numb body part.Every muscle group of my body is facing the same problem;be it shoulders,back,biceps,triceps,calves etc.Now,if i have to do any physical-work that requires muscle effort for long,my muscles pain.I had visited a doctor regarding this problem,but i couldn t tell him what exactly is wrong with me.so he gave me some calcium pills which was of no use.Now i am down n out.If any doc is listening,can you please at least identify the prob
