3 Years Later And Still In Pain After Negative Std

3 years later and still in pain after negative std tests and several rounds of antibiotics. One drunken night 3 years ago I got a lap dance and i believe the stripper very briefly licked the my glans. In fact it was so brief up until recently i thought she only teased me through my underwear. 30 hours later i found a blister on my glans. I ve been to several dra and have tested - for syphyliss, herpes, hiv, chlamidia, trich, hepatitus. I Am in constant pain with heavy sweating burning of testicles and foreskin. Aching in groin and testicles, anus and lower back. What could this be and whatvshould inget tested for next?
