I've been having this strange sensation in my chest at night, especially when I lie down flat. It sort of feels like something is squeezing or tingling inside. There isn't any pain or trouble breathing, but it does make me pretty uncomfortable. It never lasts more than an hour, and I seem to feel better if I change my sleeping position. I'm on high blood pressure medicine and recently got my kidney and thyroid functions checked, and everything was normal. I'm curious about what might be causing this. Could it be related to the medication or something else?
