I am suffering from vibrating pain in the back of my left shoulder for last 8 to 9 months which later on started going down the left hand for which I was being suggested for Angiography which I have been done with .Though there is no blockage seen anywhere but mild Ectasia with mild svdis being diagnosed in my coronary artery .now as on date the pain is not going down the left hand but still vibrating pain continues most of the time during day hrs and escalates during stress work.
