Hi, My right back muscles n shoulder region is paining continuously for 4-5days now. When I breathe heavily or cough or laugh my ribs area starts to pain. When I lay down on my bed on my back the pain increases. I go to gym regularly. But this pain started after I took break of 2 days from gym. I have tried keeping my back n shoulder area warm but it's of no use. Could someone please help me as to what should be done?
