I am having muscle pain for 5 months. The pain started from right arms with mild swelling. After having cold compress it was reduced much. But later developed pain in chest wall , shoulder, calf muscle. Feeling stiffness in paining areas. As i am doing computer job i need to sit for hours together. When i get up from chair feeling very weak to walk and sometimes even to stand. I am doing mild exercise and feeling relaxed. Can i know whether its curable. i am not taking any medicines.
