I am surprised your doc didn't send you for a chest xray just to be sure there is nothing going on. Jim's had blood clots in his lungs before and took blood thinners for it. BUT, with that said, Jim and I both have acid reflux and what you mentioned about night time caught my eye. I have woke up grasping for breath due to the acids finding their way into my lungs. A raspy voice could be the result of acid reflux too.

Have you tried sleeping elevated? Jim sleeps slightly elevated every night. He says his back feels better and he can breath better too.

Jim's neuro sent him for a MRI when he had the hug just to see if a lesion developed in the area. He was all clear.

Cindy had some great suggestions but I don't think my neighbors would care for screaming or singing. LOL

Hope you get better soon!
