My doctor suspects that i may have AVM - have had two unites of blood every two months for the last six months - i have had a endoscope, video capsule and coloscoppy, everythng is okay - also had a GI bleed a few weeks ago. Have a n appt. at Tufts next week for a second opinion - I feel fine, no aches ,no pains, nothing, but every couple of months I become tired, etc. my hemoglobin(sp) drops to 26...blood transfusion brings it up to 34... interesting, isn t it? What do you think?
