Pain on my left that has been going for two days now.

I am a 21 female living in northern Maine that has had scoliosis since I was 13. Can anybody tell me why I am having pain in my left ribs, head, AND clavicle at the same time now. First it started only with my clavicle but now it's all three.

I know I should go to the ER but every time I go for something that is shoulder pain they just take an xray and say I am fine, but now I don't feel fine and with the heat and having heartburn doesn't help.

Any doctor on patients like me, let me know please.
