Question: Hello i a few questions all relating to the same issue. I was recently diagnosed with genital warts and got treatment with Cantharidin and at the time i noticed that effect of the medication made the skin swell and blister. Later i noticed that i had a blister on my scrotum, im not sure if the doctor applied any there or accidentally dripped some. I also noticed the day i got the treatment that touching the area it was a bit sore like the other areas that the doctor treated (i also had him check down on my scrotum as well) I noticed this by scratching the area and then checking myself out but the area i scratched has changed a bit and im wondering if this is normal reaction to the Cantharidin the parts look more red and ulcer like now. And my worry is that it might be herpes (had doctor look at it today and he stated that they did not look like a typical herpes outbreak), he also stated that Cantharidin can ulcer the skin as well but that if they reappear then he would be more worried. Also my last sexual Encounter was in december and the one before that was in november and this is the first time this stuff has shown up. So my question is can Cantharidin cause my symptoms and i have read typically the herpes shows itself more often then not and soon and fairly painful. I also asked the doctor if i needed a blood test for it and he didn't seemed to worried. i have had another online doc check these pics out and he agrees with my doctor that they more then likely caused by my recent treatment and most likely do not look like herpes and i want a third opinion to make sure. i also have a few other pictures as well if you need to see more.

The dryed up ones are an earlier picture they now look more wet and yes the area at rest could very well brush up against where i was treated with the chemical are herpies usually small and lots of bumps then bigger bumps? I will upload pictures of the treatment area and what the spots look currently

What are the stages of genital herpes outbreak i thought crusty looking came after more wet open wounds (ulcers) and does it usually take almost 4 months for these types of ulcers to show up?

One last question does the crust phase come before the ulcer phase?

thats good to know as when I went to the doctors on March 18, 2015 they looked more crusty and over the day became more of the ulcer looking sores (the crust slow fell off during the day as I was looking at the sores and kind of loosing it). As well i got the Cantharidin treatment on Monday the 16, 2015 and the doctor looked at my scrotum and did not see any herpe signs. in that infection would it develop possibly blisters, crust up and then become ulcer that they are now or is it more likely that the Cantharidin spread or dripped onto my scrotum and caused this chain of events?

okay as I was not completely paying attention to what the doc was doing down there if he applied that medication on the scrotum (as he may have found a wart) would that make it more rounded? also I did have him look down there and if there was some kind of Herpes outbreak as to where we are in the possibly outbreak stages would he have seen something taking into account the short time period and what they are currently looking like ulcers (stages go, redness, to blisters, to ulcers, to scabs) and he also used a round shaped wood looking applicator.
