Dear Doctor,
One year ago,i had sex with a prostitude;91 days later,i had test on HIV,Hepatitis A,Hepatitis B,Hepatitis C.All results were NEGATIVE.But 3 months up to now,i have Urticaria on my groin.The skin around that area becomes dark.It reminds me that i didn't have test on another STDs,such as Chlamydia,Syphilis,... .I had protected vaginal sex and unprotected oral sex.Please give an advice,do i have any STD ? Do i need to have another STD test ?
Please forgive me for my bad English.
