I gave a blowjob on 13th of March. Since then, i haven't observed any blister on penis or lips.
but today (14th of April) I observed one sore in the back, left lung region and a blister at the right side of the shoulder near my neck.
Then, suddenly I started freaking out as I have been breaking these kind of blisters in my head very recently. Can they be related to any HSV situation ?
