question: When i lay down i smell chemicals and my heart sometimes pounds hard have miscellaneous side, chest, and arm pains, along with a feeling of confusion and sometimes prickly feelings going up my arms and neck. I have had a Nissen Fundaplication surgery in the past, half of a thyroid gland, multiple dilatations to the esophagus because of the Fundaplication surgery, my stomach is paralyzed. I have been told that none of it has anything to do with my heart.
