I'm 17 and I've been experiencing a reoccuring pain in my lower left abdomen and also underneath my left shoulderblade. It will apear for about a week or two and then dissapear the next. Sometimes when I inhale or use pressure I feel the pain under my shoulder blade too. Sometimes though on accasion I can feel pain in my lower right abdomen also. It isn't a severe pain but it is indeed quite a frustrating kind, sometimes it's pressure like and others it feels like some sort of bruise.

I told my mom about it and she thinks it's gallblader, but from what I have gathered I don't think that's the case.

Every now and then I do get very nauseated after eating and have vomited multiple times. I'm not sure what exactly it is, and was curious if anyone may be able to help me out.
