Had sex with another male..was receptve, condoms were used, dont know if they broke. I did not look at them. Got a weird rash on chest that would not go away with cortizone cream and was given a corticoid pill that has helped. The rash was raised the sized of my hand and was on the chest annd migrated to the bellybutton then back up to the left and it stayed and mostly vanished. The red disappeared and left with some white bump. had slight lymphnodes enlarged and dont know if a fever was present I was in warm climate. All this happened 3 to 4 weeks after sex. Could this be hiv?
