Itching Followed by Blister On Penis
I have been experiencing itching on my scrotum, which initially made the skin very sensitive, followed by the appearance of blisters. This same issue occurred last year and healed on its own without treatment. I would like to mention that I am circumcised. My recent blood report shows an IgE level of 668.42 IU/mL. I have no history of sexual relations. Given these symptoms and my high IgE level, what could be the possible cause of this recurring issue?"
