I'm 28 and when I just exercise regularly, all is ok. But when I really push it (especially when recruiting my legs into the exercise), my lips go very blue, I get really tired, and my brain gets a little "foggy". It gets hard to recover from this and keep going (even at a lesser pace).
I eat well, exercise regularly, and get a good amount of sleep. I supplement with a good multivitamin, have had a stress test, chest x-ray, heart ultrasound, ECG, blood work, lung capacity tests,...nothing abnormal shows. These symptoms began to present approx. 5 years ago.
I don't know where to go from here but other than this I can't complain about any other significant health issues.
Any suggestions? I have tried Chinese medicine, several different naturopathic doctors, and a general practitioner. Been to a cardiologist, Ear/Nose/Throat Dr. and none of them can help me. I'm ready to try anything!!
