Well, I've started up my exercise routine (seriously) again and the same old issues are starting to pop up and I don't know what the cause of them are. I assumed that it was caused by my weight but now that shouldn't be a problem. During the work out: I appear to have a super fast heart rate Because of my heart rate I tend to start breathing heavily and I feel a slight pain/sensation in my chest like I'm not getting in enough air. I tend to start spitting up and coughing at this point, with that being said, I'm pretty sure it's not asthma. After the work out: My heart rate takes a long time to come down. It still feels like I'm slightly working out even 20 to 30 minutes after I stop working out. I get light headed and I feel like vomiting. I usually fix this by laying down. Even up until a hour later, if I stand up, I nearly immediately start to get light headed and sick again. This has persisted throughout my life through various levels of intensity. This also happens nearly consistently, I had to drop Taekwondo because I hated the feeling I got after practice. My diet, throughout the years, has ranged from a high carb low protein to low carb high protein diet (Right now, I eat a "Primal diet" think Atkins but with tons of vegetables) Things I've checked: My breathing, I'm sure I'm breathing properly. Various timing of my eating and such. If I'm warming down enough I checked my blood pressure recently and, according to the label next to the machine, I was in the prehypertension zone. I think it was 120 over ..80 something. Also checked my heart rate and it was 113 resting (I had been walking around and didn't stuff earlier but nothing that would have raised my heart rate to that number). Seems a little fast. Hmm. I don't know when the next time I'll be able to go see a doctor.
