Sorry this will be a bit of reading. I have some concerns and I'm not sure if they're connected but I'll say both incase. Years ago I started having sharp pains in my lower side, now they only come when I'm stressed but it feels like needles stabbing my sides. I also have stomach problems and vomiting, the doctors say I probably have a stomach ulcer but that doesn't explain the sharp pains in my sides. Does anyone know what might be going on? Do I need to see a doctor?
