Had cythscope today ruled out ic but had red patches on wall of bladder doctor did not do byopsie! Also have swollen lymph nodes in gorin! Help plz?!?

Ask your doctor to e. Your doctor can answer such questions better. What is ic ? I would advise you not to use abbreviations as they mean different things to different folks. Groin nodes are of no consequence unless they are bigger than one inch and are growing bigger. So do not worry about it. Rest your urologist is the best guide.
See professionals... Bladder biopsy for this setting is optional. For all what you described, it would be most advisable for you to see, talk, and work with a trustworthy urologist. Best luck...
