I had a cut on my foreskin that healed, seemingly into 2 chambers . Now when I get an erection, blood seems to get trapped, resulting in a painful blister. It has been this way for over a year. I ve tried cold packs to reduce swelling with limited success. It seems like there is a hard spot that won t go away regardless of what is done. What can I do? I once waited over a week to let it heal, but as soon as I got an erection again, I felt a small internal rip and the issue returned.
