I think you should drink more water and herbal teas, avoid sugar as much as possible and take vitamin c, get plenty of sunshine(vit D), and maybe a good herbal remedy
to build up your immune system. A few years ago I thought I had throat
cancer because of some swallowing issues I was dealing with. I went to the ENT and she told me that LOTS of people worry needlessly about throat cancer and their worrying just makes things worse.
