According to my Gastro dr. he found one in my colon, and one someplace else. He said they can do a slow leak and so did my hematologist. They both are good doctors and the hematologist checks my often. I have a appointment next week for labs and then the week after to see him, unless it's more urgent then they will call me in and do an iron infusion. All this is getting to be too much with all the testing and getting no where. The cat scan the urologist did showed nothing, and when he did the cysto of the bladder that was clear but he did see some blood in the vagina and put me on estrogen cream which now I hear isn't good to take. So don't know if I should take it or not with all the side effects it shows. I only took one dose, and then the itching started and when urinating it hurt, not like a burning hurt when you have a UTI. I called them today but no one got back to me. I never had foamy urine until they did the cystoscopy and that is when that started, and he also said the urine showed blood microscopic that is why he did the cat scan. It seems like I'm going in circles.
