I have been suffering with throat tightness and pain along with chest and back pain for a straight week now, I was in the hospital for 3 days and they are thinking it could also be cardiac related, but since it was discovered I didnt have a blockage, they have kind of put me off. They have me on a heart monitor but I need something done now. I can't seem to exhale without feeling like I'm hungry for air. I also have been coughing when I inhale, I have alot of throat tightness and sometimes feel as if Im drowning, but when I cough it is a dry cough. Has anyone felt this way and what did you do? I'm desperate. I'm exhausted and its getting harder all the time.
