For the last few days I've had a quarter size pain in my back. It's a couple inches below my shoulder blade in my ribs. It's small, but intense and has kept me from sleeping. The only relief I've found is pressing it with my thumb...which gets old quickly. I've tried rubbing, using essential oils, a heating pad, and even took acetaminophen last night in hopes I could get some sleep...no dice. Any suggestions?
