<s>[INST] a couple days ago i noted a rash on the nhead of my penis and the foreskin was red and tender. now its to the point where my foreskin is tight and i cant retract it fully because its too painful and the rash is still there. ive used mild soap but its not getting any better [/INST] Hi,From history it seems that you might be having Belano-prosthitis.This might be due to not taken care properly for cleaning smegma collecting under foreskin.While taking bath clean smegma by averting fore skin gently.Go for one antibiotic medicine for 3-5 days to clear infection.Apply antibiotic cream locally.Ok and take care. </s>
