I have a chronic sore throat. Mine becomes worse when our nearby asphalt plant is operating. Might you live near a source of pollution? Mine also becomes worse when we're out in a lot of traffic. Luckily there is an air exchanger button in our car to keep the air from circulating into the car from the outside.
How i combat it is to occasionally use a Biotin product (these can cause loose bowels in me), to use sugar free throat drops but me only occasionally because they aren't good for us, and I drink a lot of water.
My doctors think my acid reflux could be causing it, so I'm paying attention to that too to see if they are correct. So far I don't see that as making my throat worse but I'll keep watching.
Fibromyalgia, CFS, MCS, scoliosis, herniated disks, spinal stenosis, osteoarthritis, sjorgens, sleep apnea, asthma, allergies, headaches. On a regiment of different supplements including sleep supplements. I eat nutritiously and do not eat foods I'm sensitive to and ever since a back injury triggered my fibromyalgia, I have been doing prescribed stretches twice daily.
