A few weeks ago I got news of a transfer with my job to a new state. Around the same time I ve felt like somethings in my esophagus, my heart feels like it s skipping a beat about every 5 minutes and when I wake up (and stretch), I feel as if I m going to faint if I continue with the stretch. So I immediately stop the stretch, and my feelings return to normal (no tingling anywhere, just extreme lightheadedness if I continue with the stretch) and only in the morning. I have a heartrate of about 75 bpm, my breathing is about 14 breaths per min. I workout (raising my heartrate to about 160) with no problems or pain. I don t feel nervous, my blood pressure is normal, don t have difficulty swallowing, no nausea or pains anywhere. and I don t feel dizzy any time throughout the day. I m making an appointment to see the doc next week. Any thoughts on what may be happening? P.S. I m also a light smoker (less than a pack a day). I know! I m trying desperately to stop. I don t always have the feeling of something being stuck in my esophagus, or at least it s not noticeable at times. It s only been about 3 weeks and for a week, I d hadn t noticed anything. I eat plenty of vegies and fruits, very very little red meat. In fact very little meat at all. I don t drink (ever!), the only drink I had this year was a half of beer. Other than the smoking, I take very good care of myself. I do 4 miles of intermittent running/walking everyday, the eliptical, then weight training. No pains in any limbs, no chest pains, nothing! According to statistics, a heartrate of between 60-100 is normal for people16 years of age up to just over 60 years of age. I ran in place for 2 minutes, my heartrate raised to about 112 bpm. It only took about 3 minutes to return to normal (or about 72-75 bpm). I was told that is preety good and normal.
