For the past month or so sometimes I notice an ache in my left upper shoulder area. A lot of times I notice it after a day at school of carrying around my backpack at school. I figured it was just from that. It happens a lot though. Especially now that I’m worried about it it’s a pretty constant ache. I’m starting to get terrified that it’s cancer. I know this is silly. But my anxiety is really starting back up, Its like I can’t be happy. I’m at a wedding typing this right now. I guess I’m just looking for some sort of comfort or reassurance. Has anyone else experienced this?
