I am about 80 pounds overweight, however I do excercise 30 minutes per day. My weight gain was caused by a lack of activity from chronic pain due to a totally separate problem. For about the past year and a half, I have had chest pressure in the same spot in the middle of my chest about 85% of the time. I also experience isolated early heartbeats, or sometimes many early beats in a row and this is of course frightening. These 2 symptoms seem to get worse and better together, the pressure and palps. I also experience heartburn, but only sometimes, and the other symptoms are almost ALL the time. I had a very extensive negative cardiac evaluation, including echo, nuclear stress, CTA, chest xrays, etc. and besides my symptoms do not get worse with exercise and I"m only 31 anyway. Is there some chance acid reflux has cause a chronic condition in my esophogus that could ALSO cause these symptoms or can there be some other cause you are aware of?
