The blood may be left over from your cystoscopy. However, if you see much more of it, I would call your uro and let him/her know. By the way, did you have distension with the cystoscopy (that's when they put fluid into your bladder during the cysto)?
As for the pain, I can't tell you for sure. I am very fortunate not too have much pain, I just have an extremely small capacity. I know that some people have pain all over the pelvic region though. Did they give you an antibiotic after the cysto? Usually just one pill, not a whole course. Let me know...
Inq,
Yes, they did do distention when they did the cystoscopy. And, they gave bactrim for infection but I didn't take it. The cystoscopy was about 11 days ago. It still hurts so bad when I urinate, I thought I would be better from the cystoscopy by now.
Hmmm, I'm not sure if you had the distension under anesthesia or not (I didn't). Usually what happens is that the bladder wall bleeds after it, which is why they want you to take the antibiotic, not to mention having the catheter put up there. 11 days does seem like a while. I think your best bet is just to call the uro and let him/her know that you are having these symptoms and that you didn't take the antibiotic. They might give you a whole course just to be safe. If nothing else, it might give you peace of mind to speak to them.
I haven't personally encountered kidney pain with IC, nor is it a "normal" IC symptom in any way. Despite the proximity and purpose of the kidneys they are (thankfully) not affected in any well documented way(s) by IC.
Urinating blood can be an extreme sign of IC, but again it is not a day-to-day one for most ICers. I would say that both these signs point to a potential kidney infection, something you will want to get on top of asap.
