"rivet-rivet"

I got a terrible cold last week. I had a sore throat and finally I lost my voice..
I went to see a doctor. As he looked at my throat, he shouted, "How awful!!!....You should take this medicine as soon as possible". He gave me antibiotics. I should have gone to the hospital earlier....
I was absent from work for two days (Thursday and Friday). I took some medicine and have slept for four days...
My voice has started coming back but sounds bad; it sounds like a frog's voice....
