snoring throat problems
Husband has sore throat around winter time help!?

My husband usually gets a severe sore throat around winter time. He went to an urgent care center and they felt he had strep throat. Test came back negative. So of course he’s put on antibiotics to help and a allergy medicine. The doctor said he had no swollen glands in his neck/ throat area but his throat area is extremely red. He went to the doctor a year ago and didn’t know what was wrong with him.
He had croup as a child, I’ve read online it’s extremely rare but he doesn’t have any the horse voice, barking cough etc.
He wasn’t diagnosed for any sinus infection problem either.
Anything come to your mind? I feel he does have sleep apnea. He snores alot and he’s actually at a normal weight for his height. he wakes up congested with a sore throat and is ALWAYS tired.
Any ideas?

It could be that in the winter, we have our heaters on and it causes dry skin, itching and even i have a sore dry throat from it. Try using a humidifier next to him all night. I found that it helped me out a lot.
