I took all of them & now he put me on Clindamycin 300 mg. I wasn't feeling better with the first antibiotic. So he switched it. What is the difference? Is the Clindamycin stronger? My Doctor says why I am in so much pain is because I have a sinus infection. But he never really checked me out. I don't have any symptoms of sinus issues. Can you have a sinus infection with no symptoms? My Doctor told me stress caused all this. He treats me like I'm crazy. Gosh I hate Doctors sometimes. They just don't care anymore. I spend so much money for nothing. Anyways 2 weeks on this new antibiotic which I have never taken. Smoovechic
