Hey Deb, I know this posting is over 8 months old, but I am curious if you still use your TENS and if it has worked at all. I have read more of your recent posts on headaches.
I ask because 4 months after my AN surgery I had a severe pain, spasm episode in my base of my skull and neck and it pretty much locked me up in extreme pain. ER visit said the muscles were so tight it was crazy. I was officially diagnosed with Chiari Malformation (which I know Phyl and a couple others have too) and know that is probably causing my issues when I get them. I had some issues post surgery, but that resolved and seemed to come back with a vengance. The severe pain 'can' come on sudden with any type of straining....sneezing, coughing, bowel movements, yelling, lifting something somewhat heavy, or even just to much physical impact. A couple neurosurgeons basically said it is causing me to have muscle tension type headaches that are also sometimes mixed with occipital migrane headaches. Most of the time the tension is in my neck and base of the skull. I have had it run down my right arm too. (all this is on the opposite side of where my tumor was)
Anyways, due to the fact I had my tumor removal 8 months ago, but this more severe pain started 4 months ago.....the doctors want me to wait & see if the pain subsides at about 1 year post surgery. My neck pain area has gotten so bad that I finally got my internest to get me into P.T. with massage for the neck and cranial, down to shoulders. They use this unit of Electrical stimulation with ultrasound and I LOVE IT! I had it used some with my back & neck for a couple weeks post AN surgery and it was what helped. (until now...I'm starting over) I asked about the arteries, etc like someone mentioned above and they said of course you need to know how to use it, etc. They are checking with my insurance about coverage to purchase and have at home, but I think it was called an Interferential unit. Supposedly it does a bit more than the TENS.
Anyways, I guess I had to ask and open back up this topic :-) THANKS, Denise
