I AM GOING TO SEE A DOCTOR FOR A POSSIBLE URETHRAL DIVERTICU

I AM GOING TO SEE A DOCTOR FOR A POSSIBLE URETHRAL DIVERTICULUM AND AM WONDERING IF IT IS SAFE TO EXERCISE, HAVE SEX AND IF THIS BULGE COULD POSSIBLY BURST? IS THERE ANYTHING I CAN DO UNTIL I GO TO THE DOCTOR ABOUT 3 WEEKS FROM NOW TO HELP IT GO DOWN?

Yes, it should be safe to have sex and exercise. I have never heard of urethral diverticulums bursting. Usually these are diagnosed by MRI and initial treatment is an antibiotic.
