Hi having a right panic. On Tuesday i turned quickly & heard my neck click & pain in my shoulder. Now the pain is in my shoulder top of my arm going into my right breast & down my back. Of course i googled & it mentioned tumours & i have terrified myself :'( anyone had anything similar? The muscle in my right arm aches a lot for months which i have been worried about too. Managed to get in the doctors tomorrow but I'm too worried to sleep
