@trishia67, Your mention of “ I also sometimes feel a radiation up to my neck when deep breathing” caught my attention. I’m chasing a different issue unrelated to the discussion here, but I have recently learned there is a nerve called the ‘phrenic nerve’ which stems from the cervical spine, C3 C5…and this nerve has something to do with the function of the diaphragm, which of course is part of breathing. My shortness of breath gets better when I lay down (so it is positional) and I do have known issues in my cervical spine. No answers for me yet but I felt better just after finding the connection between these 2 dots. Best to all who read this…I hope it helps someone!
