I've been having trouble breathing for years now, more than a decade. I just went for a swim today. I'm trying to manage my weight. I'm 46 now. I guess there are a lot of body changes. Sometimes I don't understand why other older people are thin, but I guess it's a personal thing. I was having trouble breathing and feeling motion sickness in the pool. I did feel some pain go away after an hour at least. When I got out my body was so heavy I nearly buckled. I recently lost 30 pounds. Actually, it's taken me a couple years. I think I've lost more. My pug passed away 5 years ago and I gained a bunch of weight. I kinda gave up on myself. I loved my pug so much.
I don't know if others have this experience.
I also take lamictal and Seroquel, propranolol and hydroxyzine. Sometimes I wonder if the lamictal is causing this. I know it affects the thyroid. Maybe that's why I can't breathe well.
