I would really very much apprecitate any advice from any doctors or those who have experienced anything like this. Sorry if this is a bit long or too much information for some Okay here's the start from the beginning. About a month ago(yes I know, it was stupid to wait a month), I started to have symptoms of a UTI, the burning, urinary frequency, etc. I, stupidly, ignored it and thought nothing of it really. Then about a week ago, I noticed these awful pains coming from my back, under my ribs by my kidneys. They were sharp and felt awful. A few days later, the pain seemed to move downwards. This time, and since then, the pain has been in my abdominal area and lower back. It's been a sharp, aching, pain, not sure how to describe it. It feels like menstrual cramps, but I am not even near that time of the month, so that is out of the question. I have been feeling nauseous and had mild diarehha the other day. I also had lack of appetite for about three days(I ate nothing, but I was not hungry at all, which is odd.) So I finally went to my family doctor about four days ago. The urinalysis first showed up with everything great. But then I was told to pee in a cup right after I wake up in the morning then drop it off at her office. I was also given a blood test, turned out perfect. The results from the second urinalysis came back with white blood cells, nitrate positive, and something about gluclose. She sent it off for a culture, and it returned with nothing showing up(which myself and her thought was odd.) So in the meantime, I got a CT scan, and everything is normal except for I have thickening of the bladder wall(what the doctor told me, and the receptionist(not medically trained), mentioned cystitis. So I have an appt. Wednesday morning with my urologist(had problems about five years ago) to finally figure out what is going on. Does this sound like cystitis? What other reasons why my bladder wall is thickening? What am in for wednesday? Would I might have to get an MRI or cystoscopy? I just would like an idea of what to expect and just some stuff to mention to my urologist. Also, has anyone ever had a cystoscopy, and what is it like? That thought of getting that scares the heck of out me, I cried and got upset when I had to get a blood test(I have a phobia of needles), so getting that would be rough. Thanks in advance! Edit: Kidney stones and a kidney infection have been considered, but my doctor told me no kidney stones showed up and that I don't have a kidney infection. I am also in the meantime on an antibiotic, I think Nitrofurantoin.
