have this same thing an trouble breathing while I lay down
Hi, this could be cervical spondylosis, pleuritis, muscular pain, costochondritis etc. Please try anti inflammatory drugs like diclofenac, ibuprofen etc along with hot compression and topical counterirritants.
Avoid thick pillow, If no response is seen, do consult doctor and get Chest X ray, ECHO heart done. Do you get difficulty in breathing when you lie down?
