Only when I try to swallow I have pain in my throat on the left side --in the past when this happens (a deep pain in my throat) I get a nasty cold within 24 hours. I'm trying to gargle with apple cider vinegar and salt in very warm water. Anyway to avoid the "cold" that usually follows and why does this happen? Any help will be greatly appreciated especially since I'm a Type 1 diabetic and try to stay healthly. Thank YOU!
