Hi there, I was wondering if anybody has any recommendations for me. I did work with a physical therapist through my HMO, but the types of exercises they had me doing were not compatible with CFS and so I had to stop. At this point, I seem to be making progress. I have technically had CFS for about three years I believe, although I was not diagnosed until January 2014 after having become severely ill, bedridden, unable to even get myself to the bathroom or lift a finger to type or even sit up, unable to sometimes open my eyes, etc. I am finally now making progress. I am graduating from completely bedridden to partially bedridden, but housebound. I am now able to walk myself to the kitchen, backyard, or bathroom a few times a day. However, I am severely deconditioned from nine months in bed. My muscles in my legs aren't so bad, per se, but cardiovascular conditioning is so bad that standing up is extremely uncomfortable and I can't do it for long. I really want to get to the point where I can stand up for several minutes without having to sit down. I am unable to increase my cardiovascular condition with cardiovascular exercise, because I get PEM from that type of exercise. I try to stand up for as long as I can a few times a day, but it isn't rapidly helping my deteriorated condition. How can I get to the point where my cardiovascular system can keep me upright? I'm not sure what exercises to do, and the physical therapists through my HMO don't seem to understand CFS or PEM very well. Thank you!
