I have had a horrible feeling of a full bladder for 4 days now, constant urination, but with no pain when doing so. I had my urine tested in the doctors yesterday and no infection showed up or blood. The doctor put me on Trimoptin anyway. I have been to the toilet 5 times in the last 2 hours, each time peeing normally though I can't understand why if I only had a cup of tea today why I am peeing more fluid than Ive taken in. The worst symptom is the constant feeling of fullness in the bladder. I have started to get very depressed and scared as I have read that constant feeling of full bladder is a symptom of ovarian or bladder cancer. there is no bleeding and menstrual cycle is normal and I feel fine otherwise. However today I just dont want to get out of bed as the feeling of full bladder is painful and at least in my bedroom Im right next to the loo. Has anyone else ever had this. I am so worried it is ovarian or bladder cancer and so scared. :-(
