You should see a urologist. I think you might have interstital cystisits. I have had it for 9 years. You think you have a infection and most times you don't I suffer from pressure at times and horible bladder
spasms. I have to havea cystscopy every two or three years to strectch my bladder and I take ditropan every day. If not I feel like I have to go and then can't. It's hard to get the dx unless you have uro that has treated it.
You usually have to have a cystscopy to know for sure. You can find more info under the name
interstial cystitus (my spelling is bad). Let me know how you make out.
