Hi, I have had a pretty bad cough and cold, possibly flu for the best part of a month now, which has pretty much resolved, but I now have a pain on the left side of my back, level with the lower part of my scapula. This is worse when I cough or breath in and seems to be going into my left arm. I don't feel as if I pulled anything whilst coughing. Any ideas what this could be? Many thanks, Wendy
