What might be causing this? I woke up a few days ago with pain in my neck/left shoulder which I assumed was from sleeping in a funny position. Over the last few days it’s spread across to my right shoulder and has gone a bit further down my back (to the edge of my shoulder blades. I’m also feeling much more tired than usual. There’s no numbness/tingling in my arms and I have nearly full range of movement - it’s just painful. Ibuprofen tablets and gel aren’t making any difference. Soaking in a warm bath helps temporarily. If it’s still there towards the end of next week I’ll make an appointment to see my GP but in the meantime has anyone had anything similar and if so, what helped?
