I have thoracic pain every day with my poorly back but a couple of weeks ago I was unwell with a really bad cough. I must have pulled a muscle or something while coughing because for the last week I have had a sharp stabbing pain in my ribs. It started at the front but has now moved round to my back and I am in loads of pain, right under my shoulder blade. It hurts to breathe deeply and every time I move it feels like someone is stabbing me. I've been taking anti-inflammatories all week but my pain is getting worse. Should I be going to see the doc or just rest and take some of my diazepam that the doc gave me to relax my back muscles?
