I don't feel well :/

For the last month I have had on and off pain on my left side of my stomach and in my back. The pain is getting worse and I puked last night and this morning. I made an appointment to see a Dr. but does anyone know what this might be?

Gallbladder or appendix?

could be a cyst, could be an intestine thing. Definitely get it checked.
Could be a kidney infection.

My first thought was kidney stones. I always get intense pain in my back/side when I get kidney stones.

I do have endo but yes the pain is high up so I didn't think that could be the source. I had my appendix out this summer so it couldn't be that. I hope whatever it is the dr can make the pain go away
