Hi there ~
I understand your concerns. I believe that you have had a diagnosis of urethritis
, and have a clear discharge with discomfort in your genitalia. I am glad that you had treatment for infections and are currently not positive for infection. However you do not mention if an entire batter of tests for STDs and UTIs were done. I hope that you do it as soon as you can, by consulting a qualified doctor who can order the appropriate tests after doing an H&P. I hope this helps.
Take care and have a lovely day!
