i had epididymitis and it went away with antibiotic but it came back.i think its because i masturbate because every time i do it my left testicle hurts.but it usually lasts 1 day or so.if u have epididymitis i think it would be better if u dont masturbate.
My ex husband had it very badly once, and his urologist told him to masturbate to help clear it up, and to prevent it from occuring in the future.
It took a while on antibiotics to clear it, if I recall correctly. Weeks.
