I am a 27 year old healthy adult (BMI 18.1, normal cholesterol levels, resting BP 125/66, RHR 55, etc). I have exercised regularily my entire life, combining both jogging and weight training. In the past year, I have had strange symptoms after I finish exercising. At the end of my exericse session (which typically lasts roughly 30-45 minutes), anywhere from 10 minutes after to roughly 20 minutes, I get a great deal of pressure in my ears, a loud roaring sound and hearing loss, and then extreme vertigo/dizziness to the point where I have to lay down flat on the ground, in which the dizziness/vertigo subsides within a few minutes. I have had every hearing/ear test available, passing all of them with flying colors. So my ENT sent my to a neurologist under the impression that it could be a problem related to a lack of bloodflow to my brain. The Nuerologist sent me to a cardiologist because he felt that the fact that when I lay down flat, the symptoms go away, indicating something involving my heart and its ability to transport blood to my brain after exericse. The cardiologists ordered numerous tests, including the Bruce protocol stress test. During the bruce protocol, I went to the end of the 5th stage, at which point the doctor stopped the test because my BP reached 206/101 (an rather large increase from my resting BP of 125/66). I have 9 years of education in the area of Kinesiology and public health, and I had always assumed I was healthy because I exercise regularily and eat healthy... But now I am concerned... Any advice? Or suggestions?? Should I stop exercising??? I have not recieved the official results from any tests yet (I just took two of them yesterday)... Thank you in advance for any insight you may be able to provide.
