@colleenyoung I just started therapy a couple of weeks ago and was told that it would be a gradual progression over 9-12 months. So far I have been walking in the pool with water up to neck level for 30 min each day(this forces diaphragmatic breathing), using a little device called a breather 2 times per day, practicing box breathing and deep breathing exercises multiple times each day. Also when very symptomatic, either breathe into a 20 oz bottle with an eraser sized whole cut into it near the top of the bottle or place half of an Airborne effervescent table directly on your tongue and breathe through your mouth as it foams and fizzes . Both of those options give you a CO2 quick bump. I also started using an APAP machine last week to aid in overnight breathing. I start respiratory PT next week. So far I’ve seen a slight decrease in symptoms. I don’t breakout in a sweat every time I eat, my arm doesn’t fall asleep all the time, I’m not as shaky, and my heart rate is getting back to a more normal level so I don’t feel as anxious. My chronic fatigue, brain fog, and GI issues are still very present but I always carry the Airborne tablets with me and they do provide a very quick recovery response. The other key is pacing your activities and resting frequently. Cardio workouts or anything that raises your heart rate is advised against since it uses CO2. Pool walking, walking, stretching exercises, and mild yoga are encouraged.
