In a flap as I saw a horrible doctor yesterday who's got me upset. I'm twenty and for a while have been suffering from persistent urinary issues e.g. pain on peeing, difficulty peeing. The doctor (urologist) said he wants to do a cystoscopy within four weeks to see inside my bladder and I am now terrified that he thinks I have cancer. Don't know what to do, he has cancelled all the other hospital treatment I am getting for gynae problems because he says I don't need it. I'm so scared, please help.
