i went to a massage parlor and got a hand job only. 2 days later developed a rash on penis glan. I immediately went to urgent care and got full std panel done and it came back negative and i was told it could be fungus infection and used clotrimazole. no improvement for 10 days. so i get tested again and all tests came back negative. doctor prescribed econozole nitrate. 4 days in and no improvement, i went to skin doctor and he prescribed cifron + mupirocin ointment. slight improvement for a week. so he added azythromycin+gentamicin to the existing treatment. lot of improvement but now i see dark circles underneath skin, like if someone punched your eye it would be dark inside and the outerskin is going away in a circle fashion. doctor also did a HSV PCR test and came back negative. not sure what infection i have. any experience similar infection? please help!!!
