After using catheter, the whole day I suffer with uncomfortness and little pain every time I urinate. Why is that? Any solution for this problem?

Time. "azo, " "cystex, " "uristat" or similar can help numb the urinary tract if discomfort is severe, and are all over -the-counter. Should not use for more than 36-48 hours. If discomfort persists after med wears off, then should be seen by dr / urologist for exam.
