I have an unusual pain which radiates around my left shoulder and left rib cage. I cannot breathe deeply - well if I try to it hurts. I had a car accident about ten weeks ago - a car ran into the back of me and I had whip lash. I only had two sessions of physio because it happened abroad and i did not think i needed it. I was wondering if there is a connection. I am very fit for my age and last night performed in a show and the symptons only started late last night and continue now. It is cold in the UK and today I found it hard to keep the core of my body warm.
