Mid-back pain after using CPAP

I have been on a cpap machine for a week after being diagnosed with 'profoundly severe sleep apnea'. I had apnea 62 times an hour for up to 2 minutes. Since being on the cpap my whole body and mind have been reawakening, But the strangest thing is that I have been getting very tired muscles just doing daily tasks such as carrying the shopping in and loading the dishwasher. Has anyone else experienced this. I must also note that I have been taking anti-psychotics and anti-mania drugs for the last 10 years and am thinking it could have been a result of being chronically sleep deprived for so long. I saw that chronic sleep deprivation can give you more energy, how does that work!? I'm not overweight and have previously been reasonably physically compitent, but a 45 minute walk the other day nearly killed me whereas before it was easy and I used to walk at a much greater pace. Any thoughts? By the way, thank god that I changed doctors, I was complaining about sleep apnea to my old doctor for two years and he did nothing! I saw a new and younger doctor and he sent me for the sleep study, they said its the worst case they've ever seen and were surprised that I wasn't overweight and my daytime sleepiness wasn't more.

Hi, from up over . You're probably feeling your thoracic (chest and back) muscles stretching from use for the first time in a while because of dealing with more air getting in... but that should go away relatively quickly. Another thing - doctors just love telling patients their case is 'the worst I've ever seen', but in fact there are very many people (lots here) who've had much higher results than you... so don't take what they said to mean a whole lot! Another thing is that your level of pressure needed for Cpap has no relation to how serious or not your study results are... it's all about your individual airway/inner throat size and you might only need a low pressure to keep yours open, and someone with very mild apnea may need a lot of pressure to keep theirs open. If you have other questions or concerns, please come back any time.
