I have dry eyes, nose and throat. my throat hurts and swallowing is painful. any advice on how to remedy it or why it could be hurting?

Allergies: Could likely be allergies, given this time of year. You can try a nasal saline at least 2-3 times a day to moisturize your nasal passages. If congestion, a nasal steroid like Flonase is very useful and could help with post-nasal drip symptoms. Antihistamines also could help, like Claritin or Allegra. If you have fevers, need to consider infection, warranting antibiotics. Hope this was helpful.
