I have been suffering from daily pressure headaches for over a year now. I now have new symptoms related to insomnia. It is weird, when I am trying to go to sleep, I get a hypnic jerk reflex. This happens 5 or 6 times and then my body just gives up on sleep and I usually average 3 hours of sleep per night. It is awful. My doctor prescribed ambien and that is helping a little bit (I can usually get 5-6 hours on it). Just wondering if anyone else has this symptom. In addition to this symptom, I also feel as though my skin is "crawling", severe itchiness all over my body at night mostly, but also during the day. This is also a new symptom. I am afraid that I am having seizures or something (or maybe sleep apnea). Getting a sleep study done soon. Also, trying to get my neurologist to approve a CINE MRI and get a referral from my PCM to see Dr. Trumble in Orlando.
