I recently suffered chest pain radiating to both arms. Arms were very painful to the point of feeling my pusle in both. I went to the ER and had a Nuclear Stress test, chest x-ray and enzyme blood tests every 6 hours. All tests were fine showing no significant relation to a cardiac issue. I am still having this problem and following up with my doctor next week. The pain in my chest is a burning stabbing pain that goes down bothe arms, but more to the right than left.
Thanks for your question on Chat Doctor. I can understand your concern. Since your extensive cardiac work up is normal, possibility of HERD (gastroesophageal reflux disease) related pain is more in your case. HERD is due to laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the esophagus and cause the symptoms of burning, stabbing chest pain. So do following things for better symptomatic relief. 1. Avoid stress and tension. 2. Avoid hot and spicy food. Avoid junk food. 3. Avoid large meals, instead take frequent small meals. 4. Start proton pump inhibitors and prokinetic Chat Doctor.  5. Go for walking after meals. 6. Quit smoking and alcohol if you have these habits. Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
