I was diagnosed with Chlamydia about a week ago. They gave me Azithromycin, 4 tablets at 250mg to take all at once. I took them and have severe stomach cramping and nausea, and ended up getting sick about 45 to an hour after taking the last pill... hoping that I would have already digested it before I got sick. The stomach pain lasted the rest of the day. It's been about 3 days now since I have taken it, but I still have that "burning" sensation after I urinate. How long does it take the medication to fight off the bacteria? Is it possible I still have it and it didn't work? How long does it take for symptoms to subside?
