<s>[INST] I m having a rapid heartbeat, but no chest pain or heartburn. I just feel very jittery. My breasts are sore. 45 yr old male with no history of heart problems. Had EKG 1 month ago=normal. Taking Restoril, Wellbitrin, Percocet, Saphris, and Fentenol patch [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Since your ECG is normal, no need to worry about heart related diseases for your chest pain. Sometimes stress and anxiety can cause palpitations, chest tenderness (soreness) etc. So better to consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. You may need anxiolytic Chat Doctor.  Don't worry, you will be alright. Avoid stress and tension, be relaxed and calm. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
