Anything I can do to help a very irritated throat? Home remedies too? Ate something that bothered, ever since then it hurts to eat. Wks to repair?

Needs exam. I suspect you have tried all the usual things: lozenges, salt water gargle, ibuprofen/naproxen/aspirin, warm fluids such as chicken broth, lots of water, avoiding alcohol and caffeine.MOST IMPORTANT, if it has truly been weeks it is time for an expert exam to make sure something more sinister or serious isn't going on. Could be reflux or chronic rhinitis.See your doctor/ENT specialist. Good wishes.
