I've had a previous suspicious episode of herpes with very painful blisters on my penis about 18 months ago. After a couple of episodes of unprotected sex I recently felt very unwell with fever, backache and general fatigue and went to get tested for everything - all negative so far but now i've developed flat purplish-red spots on the glans of my penis. Very rarely does it feel itchy or uncomfortable but I'm not sure if all of this could be a herpes flare-up or if I should continue to panic waiting for my HIV test in 3 months time? Also my doc didn't want to test for syphilis - is that a possibility?
