Regarding the urinary tract infections. I had them for years and had all kinds of test. They couldn't find anything wrong with my bladder or my urinary tract. A couple of years ago my urinary tract infections went away and haven't come back yet. My son and I also have problems with reoccurent sinus infections and ear infections. He has had to have surgery.
My sister-in-law has the worst case of CFS/ME in the family. She gets urinary tract infections so bad that they spread to her kidneys. She also gets Kidney cysts and stones. She has had to have her ovary removed because of cysts and she had such a big problem with her lymph nodes swelling and getting cysts that she had to have some of her lymph nodes removed. Most of what was removed was under her arm pits. She has also had infections so bad that she has been in the hospital for sepsis more than once (infections that have spread to her blood). This is why she is seeing an infectious disease doctor. Things for her were so bad that her doctors finally decided she must have some type of infection lowering her immune systems ability to function. However, they never did figure that out and she is convinced that her illnesses are because of past trauma.
Oh good god. When I hear about your sisters suffering.. Geez. My heart bleeds for her. It does show however that this XMRV-research MUSt be right on the money! If they can get the rootproblem disapear by treating her XMRV, then she should get rid of all the other symptoms too, right? Let me ask you: how much does she sleep a day? Does she have POTS? Stupid questions maybe but it makes me so curious. I've read about xmrv and the link to cancer, so what you're telling me makes sense; that living with an untreated infection in your body of course creates other illnesses since the body can't take it. I'm VERY curious about your sister and would love to hear more!
