<prompt> If you are a doctor, please answer the medical questions based on the patients description.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.  <response>: Hello! Welcome on Chat Doctor! I read carefully your question and would explain that your symptoms seem to be related to anxiety. Nevertheless, some other causes should be excluded first. What are your blood pressure and heart rate values? I recommend consulting with your GP for a careful physical examination and performing some tests: -resting ECG -chest X-ray study -lab blood tests complete blood count, thyroid hormone levels, fasting glucose. A brain EEG and MRI scan should be done to exclude a possible nervous system disorder epilepsy seizures which could be related to this symptomatology. If all the above tests result normal, the main cause to be considered would be anxiety. Hope to have been helpful! Best wishes,
