Last night I had possibly the most severe pain so far which woke me up several times.
It started under my left shoulder blade and radiated to the front and sides of my upper ribcage and all the way down my arm. I tried changing positions but it didn't help and at one point I did think I needed to call an ambulance.
I got up a second time and took a naproxen 500mg and managed to get back to sleep. No pain this morning but it was really worrying.
Has anyone else had this and is it likely to be related to inflammatory arthritis?
