I am a 27 year old man with prior cocaine use. Its been 2 years since I have used any drugs at all. About a month ago I started getting these chest pains on the left side of my chest. They last for a few seconds and are a squeezing type, sometimes sharp. Because I have a anxiety disorder I got so nervous I went to the ER and they did EKG, bllod work and everything came back normal. But I still kept getting those pains. So I did a holter monitor for 24 hours, as well as a ECHO-STRESS test. Those also came back normal. After 5 weeks I am still getting those pains and they are driving me crazy because I still think something is wrong with my heart. After those tests would it be safe to say this could all be my panic disorder?
