I felt my upper arm sore the other day, and today i have the pain around my shoulder, and neck, and the top of my arm (between shoulder and elbow feels really uncomfortable. I can't lift my arm, even putting my hands on my hips hurts, and the slightest movement seems to make it worse. Any tips will heat or ice be better. I'm supposed to be doing housework, but its a good excuse not to. Also, meant to mention pins and needles feeling in arm as well
