A few days back,I wasn't in a good mental state.I was crying.However,after sometime I could feel a slight pain on the left side of my chest.The pain was such that whenever I move,there is a slight pain on the left side.On the very next morning,my left arm,shoulders and back of my shoulders started paining immediately after I woke up alongwith that slight pain.I applied volini on my elbow joint and the pain reduced.However ,that slight pain is persisting even now.It has been 4to 5days already.Whenever I move,I can feel a slight sharp pain.Why is it happening?
