Another medical adventure

Without going into all the awful details, I've been experiencing some rectal bleeding lately (today really bad-the other day I just started noticing it). My GI sent me for a STAT CBC (blood draw) to check my red blood count this morning-and everything was thankfully fine with that. I've been pretty disoriented and "dizzy" for about 2 weeks now-kinda hard to explain. Anyway, they are scheduling me for a colonoscopy to see what's going on. They are looking for endometriosis that may have penetrated my colon-that's the guess about what's going on with that now. Very scary-and I am very freaked out. It is a pretty rare thing for the endo to completely penetrate the bowel wall...but, it's known to happen with my stage of disease. So, here we go again. I don't know when the colonoscopy will be scheduled for, but I am going to make a push to have it done this month, before I start my other treatment. Please keep me in your thoughts. I thought my nightmare was over...or at least had answers.
