Sinusitis
"I was prescribed these for an ongoing sinus problem, I&#039;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&#039;ve had infected sinuses. I&#039;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."
