Tonsillitis/Pharyngitis
"Have tonsillitus and mouth ulcers all over both sides inside my mouth. Previously this had turned into something worse so put straight on this antibiotic as I cant use penacillin. I&#039;m on day 3 of taking it. Hasn&#039;t helped at all so far so wouldn&#039;t say its fast acting in my case. Paracetamol works on the pain but thats the only relief I get. I have been getting night sweats but not sure if thats a side effect or just that I&#039;m fighting an infection. UK user prescribed on NHS."
