Question: What are the electrical impulses in the brain? if I feel such things whats going on? it is felt in various strengths.

The events occur at night mostly,I awake due to need for bathroom use and it seems to occur when I have a couple hours sleep and since I usually wake two to four times a night for passing of urine, it would normally occur almost every night the past few months. I do not feel this if I sleep well meaning my wake up was once and occurred late in my sleep.I use a cpap machine due to sleep apnea.I use it every night about 5-6 hours. My pulmonolgist last week had no answer for me. In the past and I mean 30 years I have had sharp instance of a shock feeling once in a great while like once a month.Those seemed to have stopped since this nightly incidents started.


Answers to questions-I awake with need for urination after 2-3 hours sleep and I feel this constant feeling in my brain/head that a electric switch is being flipped.This can happen a couple times a night in the early in early sleep after 4-5 hours sleep it usually does not occur.The action I mention continues till I fall a sleep again. So that is probably 10 minutes in bathroom and awake time These usually occur only at night,although the last two days I have had the feeling in the daytime and only in seconds. I have not fainted. Generally my sleep the past several years has been lousy due to frequent urination. I had this before and after prostate cancer which was eliminated by seed implantment 10+ years ago. I have sleep apnea and use a cpap machine every night. My pulmonologist was visited recently and had no suggestions. It really concerns me.
