I have just received mine and every time I try to use it, I get cramps in my toes and muscle twitching in my legs. At first, I could only use it for about 15 minutes. After 3 days, I’m up to about 40 minutes, but I do not fall asleep and I can’t keep using it after the twitching starts. Once I turn off the machine, it takes about half an hour before the twitching subsides.
My provider is very supportive. She’s changed the settings twice and I’ve noticed some improvement. I have a ResMed VPAP ST.

I have been having health problems since October. Symptoms im having are…muscle pain, weakness, sudden loss of strength, burning pain in joints, muscle spasms and cramps, fatigue,clumsiness like dropping things alot, unsteadiness, tingling in my legs and arms…my family doctor did blood work which came back normal, at first he thought i had fibromyalgia until i started having muscle weakness, he ruled out sleep apnea as I dont snore much and sleep fairly well nor do i have very many of the symptoms. He sent me to a neurologist as he thinks i have a neurological disorder…the neurologist says he thinks i have sleep apnea and scheduled a sleep study test, ive talked with others who have sleep apnea and they say I need to see a different neurologist and get a second opinion…has anyone else had these problems with sleep apnea???
