Lou, I'm glad they have sorta pinpointed what is wrong with you. Now you just have to find out what is causing that.
My B-I-L takes like 5 Motrin at a time and he has internal bleeding somewhere and needs a colonoscopy. I think his is caused by the # of those kind of pills he takes at a time and regularly. That's a long time to wait for your test. But you are on the right track to getting to the bottom of your health problem.
Take Care....
