Hello I am 18 and about 3 months ago I feel burning pain between my anus and genital only when I ejaculate, about 2 weeks ago I went to the doctor and he gave me 1 week, 2 times a day 2 pills at a time morning and evening Ciproflocaxin and now the burning sensation is gone but I still feel a bit uneasy when I ejaculate, after ejaculation I feel a little pain right on top to the left and right of the base of my penis(not sure if its related) and I'm scared that it might be something more serious ? When the doctor checks he didnt take urine sample or anything, he just feels where the burning(pain) sensation was.
Thank you,

Very much concern
