Hi I recently had a pimple looking thing on penis I popped it and now it has become red and a little swollen kind of looks like a mosquito bite now. I recently have been tested and ame put negative. Should I Wait a little while to see if it heals or should I be worried?

Yes you should wait a while, since your test results are negative. However if you wait for about 1 week and a half or so and it`s still there u need to go back to yous doctor, he/ she must prescribe an antibiotic cream or ointment for you to put on your penis.

Good luck :)
