It started as a quarter sized hard mass extending from the urethra into the vagina. It burned and caused frequent urination. I was seen at er and they referred me to gyn. She don t know what it was but gave me doxycycline to see if it helped. The mass has sort of extended now in to the vagina a little more and is still hard. I have an appt with a gyn July 1st. I believe it is a urethral diveticulum.
