Brain Tremors/Shivers

[AAH Lady]

I've had anxiety issues for more than 10 years now and have been on Buspar and was switched to Lexapro a couple of years ago and the dosage was increased to 20mg earlier this year.  I haven't really experienced any problems associated with the medication that I'm aware of, but in the last month I've had terrible issues with my back (first a sprain in the lower left side and then in the last two weeks, my degenerative disc in my neck has been troubling me again after two painfree years, due to steroid injections two years ago).  At the moment, I'm waiting to be scheduled in for another injection into these nerves next week.  I've been taking Lexapro, Methocarbomol, Ethodolac (Genertic Anti-inflammatory), Allegra D and Tylenol PM.  In the last week, I've been experiencing these strange and unusual brain shivers, like a little tremor in my head more frequently than ever before.  I have had a couple of these in the past when I missed my anxiety medication, but I haven't missed any doses and the increased frequency of these little "shivers/tremors/sparks" are beginning to trouble me.  I don't want to worry over nothing, but I also don't want to minimalize something that might be a different issue (maybe brought on by my neck pain or the medication I'm taking).  I've taken all of these medications for several years (have severe sciatica in left side since I was 18).  So I don't think it's medication related.  Any thoughts?  Am I worrying over nothing... Is this normal?

Fascinating... I think I may have found the answer on Wikipedia... "Brain zaps" are said to defy description for whoever has not experienced them, but the most common themes are of a sudden "jolt," likened to an electric shock, apparently occurring or originating within the brain itself, with associated disorientation for a few seconds. The phenomenon is most often reported as a brief, wave-like electrical pulse that quickly travels across the surface of (or through) the brain. They are sometimes accompanied by brief tinnitus and vertigo-like feelings. Immediately following this shock is a light-headedness that may last for up to ten seconds. The sensation has also be described by many as a flashbulb going off inside the head or brain. Moving one's eyes from side to side quickly while open has also been known to trigger these zaps and sometimes causing them to come in rapid succession. It is thought to be a form of neuro-epileptiform activity. [1][2]

As withdrawal time increases, so do the frequency of the shocks, before they wane completely. At their peak, brain zaps have been associated with severe headaches. They may last for a period of several weeks after the last dose and usually resolve completely within a month or two. However, anecdotal reports of "zaps" during a protracted withdrawal are known to last a year or longer.

I have herniated discs in my neck and a bulging disc in my low back. I know you get different sensations from the nerves in other parts of your body, right now I have been having the tingling in my left calf all day. I was thinking maybe you should look up these symptoms according to your neck problems. there are so many things that can be brought on by that. Does it come on randomly or is it when you have your head and neck in certain positions.Good luck and I hope you feel better. Let me know if you find something out. I would be curious to hear about it. I have alot of problems with different things too.Also there is a back forum, try checking on there, maybe they can help. I have posted on there a few times and have gotten some good replies.Lots of neck and back issues you could read up on.
