I m having a strange feeling like fluttering at the end of my neck (tie knot location), but not all the way into my chest, also feeling like I m out of breath. I went to the hospital on 08/21/15, thought I was having a heart attack, due to severe chest pains and couldn t breath. They had to give me pain medication, but said that my heart and lungs were good, possibly pulled or pinched something. On Monday 08/17/15, when I opened my eyes my room was spinning like a merry go round. Went to the doctors on Wednesday 08/19/15 and was given cortozone for my ears. Now I have this fluttering feeling going on and don t know what to do or where to go.
