So this morning I woke up with pain in my underarms (both). It only hurts if I touch it or if I press my arms against my body. The top of my back at the left side hurts too. Also had some minor chest twinges that come and go, these have happened numerous times before though.
For some reason I googled this and I've decided it must be cancer, and I'm now completely and utterly terrified. Cant get a doctors appointment til next week and dont live near a walk in centre. I cant stop worrying to the point im sobbing. 
Has anyone had this type of pain turn out to be harmless?
