I have just recently started using CPAP and after the first couple of nights started waking up bloated and terrible back pain. I have to get up and move around for it to stop. I have stopped using the machine and the pain stops. It feels like my back and stomache are having contractions.
I went to my specialist who said that for some reason I am taking air into my
stomache instead of my lungs and the pain is being diverted to my back.
Has any one else had this and been able to come up with a solution. I have been told because my apnea is so bad 125 times an hour that I could lose my liscense. :
Welcome to the forum
The bloating is called Aerophagia, air get trapped in the stomach which causes pain and gas.
Sleeping with your head aligned with your body can help and you can try elevating the head of the bed.
Try to set CFlex at 3 so you get maximum pressure relief when exhaling.
The other thing ask your doctor to adjust the pressure down so you can get used to the pressure
and as you start to feel better the pressure can be adjusted up gradually
You've already gotten an answer to the aerophagia. The only thing I can add to Zonk's post is that many people on this forum have said that it tends to fade over time as you continue your CPAP therapy.
I have the same problem with back pain. If you search the internet, you won't find this as a side effect on any of the "medical" sites, but you'll find a lot of posts from people on the various forums. In my case, the pain is muscular, not skeletal. I don't know why this happens to us and my only guesses are:
1. My wife says I used to flop around like a fish, now I stay in one position and only turn a few times a night.
2. The mask head gear may be making us keep our heads at a weird angle. I haven't tried any of the xPAP pillows for sale. I'll let others comment on that.
3. The weird equipment we're now wearing every night is just keeping us tense as we sleep.
4. CPAP aliens are beating us with a baseball bats while we sleep.
I really don't know and haven't found any good explanation. One guy did postulate that the pain was caused by the release of toxins that had built up over the years as we slept poorly. Don't buy that one!
I started doing flexibility exercises (okay, basically yoga) about three hours before bed time. This helped A BUNCH and I can really tell if I neglect to do them. The chiropractor helped, but the best thing I did was a get a new bed. It's a "snooze digit" (veiled commercial reference), very pricey but it really has helped.
I understand waking up after only four hours sleep in enough pain that you can't go back to sleep. All I can tell you is that I still felt more rested with four hours of CPAP sleep then nine hours without it. It has gotten better over the months, but I still have my bad nights, and I don't think I've gone over 7 1/2 hours sleep since I started therapy about a year ago.
Keep posting here. Let us know how you're doing.
