What can you do if you throat hurts because it feels dry but you drink water and it doesn't help?

This sound like a throat infection Either get some disinfectant lozenges to suck on or (and this works very well and has been used for a long time) gargle with salty water every 2 hours, don't swallow the water. naturally if the throat does not start to get better you may have to see the doc for some antibiotics.
