I don't smoke or drink. Having internal vibrations for 3 years. I did a sleep study and I didn't have vibrations for a week and a half after sleeping with cpap. They started back slowly and now are back to every night. Last night they were in lower abdomen, pelvic area. My neurologist wanted me to take Fycompa but I read up on it and decided not to. I don't see him again until May. They wake me up between 1-4 am. Thing is, I can lie on bed for 4 hours watching TV and not have any. They happen ONLY AFTER I have been asleep. I don't understand why, after using cpap, they stopped. I told neurologist that I think I injured my phrenic nerve taking my morning meds and swallowing a huge gulp of air. That's a symptom. It started within 2 days of that happening. My neurologist thinks I'm crazy, don't they all?, I KNOW it's my diaphragm which makes sense having air forced into my lungs with the cpap and the diaphragm controls your breathing. The cpap is on back order. I'm calling them today. If it'll stop these vibrations, I'll sleep in it. It's the nasal one so I don't feel like I'm suffocating.
