I have a gastric band & I have constant pain in the lower stomach like a stitch,?

I have had a constant pain in my side, it feels a bit like a stitch you sometimes get after running, this hasn't been brought on with exersise or over exertion, it feels like someone is wringing my stomach out with their hands.
I have a gastric band, which I got 2 & half years ago, it has been fine up until recently.
about a month ago I vomited blood, first it was black & grainy, then dark red, like wine. I went to hospital regarding this and had an x ray, I then had a barium x ray which I paid for, just for my own piece of mind, they said everything looked normal, and the blood was probably due to a burst blood vessel, but now i've got this pain and am really worried that something is seriously wrong.

Booboolamore, call the doc that did the banding and ask to be checked out. Anytime blood is found it should be fully investigated. You may need more than just an x-ray to find out what's going on. Take this a step further than going to the hospital.
