Hi there. I have a lump on my right shoulder. It feels bony but is moving around. It's not a cyst as it quite solid. It was uncomfortable for last few wks but now it is sore as is top of my arm. I am also getting shooting pain n right hand. My neck and back of head also sore. I have arthritis and costochondritis but the pain is different. I am tired due to arthritis but tired and nauseated the last few days. Seems to have passed though. Not sure if I should be worried.
