Hi

I am a 33 year old women. Over the past couple of months I have had the need to urinate alot more frequently, sometimes every half hour or even less. I have constant bladder pressure but no pain or discharge. As soon as I go to the toilet I feel the need to go again. The only other thing is a couple of times a week I also experience some diarrhea and I have felt warmer than usual.

I have been to my doctor they have done blood tests & taken urine samples which have all been negative.   I do not have an infection.  They have just told me to drink more water and less fizzy drinks and see how it goes over the next couple of weeks. It is really starting to get me down!
Please help.

Many thanks
Isabel
