sinusitis
"I was prescribed these for an ongoing sinus problem, I'm not convinced it is an infection as my mucus is clear and not bright yellow as it has been in the past when I've had infected sinuses. I've experienced horrible side effect, horrible taste in my mouth, nausea, fatigue, muscle ache and just generally feeling ill. I would stop taking it but if it is an infection it will probably make it worse so just going to buck up and finish the course. I would not recommend these antibiotics to anyone."
