I feel as if I've constantly got a UTI! Any time I have to use the bathroom I have a lot of stinging and burning, especially when I'm finished. I even feel like I have to go when I don't and I periodically feel random pains in my bladder area. I've already been on medication for it in April, but I've been finished for about 2 weeks now and haven't felt better.
