Symptoms are difficulty sleeping due to shallow breathing (RDI 3.7, AHI 3.4 and Spo2 minutes less than 89% 127.4), low grade fever, headaches, fatigue, muscle aches/pains, joint pain, average heart rate during sleep 79.1 bpm, with possible bigeminy and trigeminy and altitude sickness. I am 68 y/o and have been an avid cyclist, very physically active. I now have no energy to think some days. Thanks, Jeanne Galvin
