i am 21 this year and preparing for my final examinations. 2 weeks ago i experienced backache and the backache is relieved if i change my posture of sitting or while lying down and it disappeared after 2 days. 2 days ago, i experienced muscle ache at my right arm and my right thigh and it is relieved after applying some oilment. And this afternoon i experienced muscle ache at my right forearm and it too relieved after applying oilment. Should i be concern over such pain.The pain is like something pressing again my arm.
