about throat

I have pain in my throat and my tonsils are swollen. My throat feels very sore and scratchy. It is difficult for me to swallow food and sometimes even water. I also feel irritation in my throat while speaking. The pain has been there for a few days and it is making me uncomfortable. Sometimes my throat feels dry and burning. Because of this, I am not able to eat properly. I think it may be tonsillitis. Please check my throat and suggest the proper medicine for it.
