" Perineum problems "

[Racine45]

Hello, I am a 45 yr old man
About 8 weeks ago while taking a shower I noticed a red spot (blood) on my wash cloth. I felt between my legs where the spot came from and I felt a lump. I squeezed it and a fair amount of pus/blood came out. The lump got smaller the next couple of days after I had taken some antibiotics which I had leftover from a previous sinus infection. It went away until a week ago. It came back so I squeezed it out again but this time it was a smaller amount. I laid down in bed and then I felt it draining more so I squeezed it more. It sealed itself up pretty quickly but it left my perineum swollen in an oblong shape that went down to my rectum/anus. It became painful and bigger so I went to the Dr., then he prescribed me (smz/tmp DS 800-160 Tab) to take twice a day for 14 days along with pain meds. It's been 2 days. It's gotten smaller but the pain has kinda went down to my anus and I feel a bit of pressure of and on. Previously the pain and tingling sensation was in my scrotum and penis. Last night I did noticed that I urinated 4 times in 20 to 30 minute increments. It was kinda warm coming out but nothing serious. I mean .... I still get hard and I am able to have sex pretty normal. Has anybody else experienced this ? What is it ?

Thank u !
