I'm a 33 y/o m going to have a cystoscopy in a few wks. Pain hasn't been fun lately. Can a cystoscopy make the pain worse depending on the cause?

Maybe. A cystoscopy is simply running a camera up into your bladder to take a peak. The bladder is filled with water during the procedure so there could be some residual soreness afterwards. However, things shouldn't be worse after they get done.
