I've had urethral burning/pressure for 6 mo. Cultures are neg for uti. Cystoscopy shows redness. Protein 30/wbc 8-10. Atarax and OTCS don't help.?

One idea. Some folks get this just from spicy food, especially those hot little peppers. Could this be you? Glad you had cystoscopy, I trust that interstitial cystitis was ruled out, and that any suspicious lesion was biopsied. Good luck .
Urinary symptoms. Were you told that you have interstitial cystitis or is it a result of urethral injury? It is not a easy discussion here. You should see your physician about it.
