One day i had a blackhead on my penis so i tried to pop it. Only a little bit of puss came out. Later that day the bump got bigger. The next day i squeezed it and alot of puss came out. I put peroxide on it with a q tip to help it but idk if that's working the bump is still swollen. How can i make the swelling go away? It looks like a mosquito bite. Its not flaring or red it just a swollen bump on the shaft on my penis.
