Hello folks,Last friday Feb.22nd I recently had risky behavior and someone(a person who I don't know) perform unprotected oral sex on me.

The Tuesday after I gotta funny weird and mild Itchy feeling in my penis and anus, I went to the clinic that Friday and Dr. have told me that I had chlamydia. She gave me zithromax 2 500mg pills took them I was fine until side effects started on saturday. I got light-headed and sore muscles, Sunday got a lil better I had an unpset stomach with sore muscles(dizziness went away) I used the bathroom to Poo and noticed my anus was very itchy. Can someone please tell me how long it takes for zithromax to kick in?
