So to preface this post; I am an EMT so I'm kinda looking for a differential diagnosis from this.
24 y/o Caucasian Male, 6 foot 180lbs.
Pertinent PMH: Hx of infrequent Hemmorhoids. +steatocystoma multiplex. Body hair depilation has given ingrown hairs & folliculitis. STD panel negative (G/C, Hep series, HIV/AIDS, HPV, Herpes Simplex) sexually active with only one person.
Medications: just finished a Z pack for cold/resp infection
Presented this AM with "prostate pain" to the pereneum. After 8 hours, pain progresses to a throbbing pain. Upon palpation to pereneum, a subdermal mass (slightly spongy like that of a lymph node when inflamed). There is referred pain to the prostate when palpated with no rebound tenderness. The site has no redness, drainage/discharge, crustation. Of DCAPBTLS pneumonic, only tenderness and (almost negligible) swelling.
Based upon these findings, I have it ruled down to folliculitis vs. a cyst. The pain mimics that of past underarm folliculitis, however due to the location of the inflammation, drainage or lancing isn't possible for a solo act.
I have doxycycline available, and was going to restart it to see if this lump disappears (along with witch hazel for anal-rectal cleaning). Any help would be appreciated!
