Hi Christi,
I also have and get that pain, and to be honest I think it's the worst of the pains I get. Outdoors in any breeze, I always try and cover my ears somehow, and I've avoided swimming for years now. Sadly, swimming used to be my favourite thing :(
Mine too feels like an ice pick - but switches between repeated stabbing sensation or just like the ice pick is lodged in my temples. It is one of very few pains I get that will always drop me to the floor very literally.
To answer your question of the temples being on the trigeminal nerve - very much YES. Behind the temple bone also is where the Trigeminal Ganglion lies, the centre from where each of the three main branches stem from. I know this from my pain clinic specialist from where he's done different kinds of nerve blocks - he explained all this anatomy to me.
My Neurologist, well now ex-Neuro is an idiot and really didn't know anything about TN, I often figured I knew more about TN than he did. An often we do until we find the really good Neuro's who have studied and know and listen to us.
TN takes many forms, presents pain in different ways. I was diagnosed at age 30 after already suffering a multitude of face pain symptoms since age 17. But even since age 30, when I learnt what TN was (I'm now 37) I would have to say the range of pain sensations still continues to shock and surprise me. They are: zaps, cattle prod, stabbing, drilling, wrenching, twisting, burning :( , the ice pick, creepy crawlies, pressure bands, one that feels like insect stings of the worst kind and so on ......
If you experience the pain in your temples on both sides at once, that is a curiosity - Christi, do you have TN on just one side of your face or both? I have it on both sides - and though every doctor says TN can only attack on one side at a time - I know that is not true, as I have had attacks of TN on both sides simultaneously and it's a nightmare.
When the temple pain is involved these days, it also includes both my ears, and one upper cheekbone, directly below the eye. It is the worst and longest lasting pain I get, the pain lasting never less than 12 hours - the longest single running attack going for up to 2 days, before I get driven half mad from the intense pain and lack of sleep and go to the ER.
To think alternately, the Occipital nerve at the back of your neck runs up and around the sides of your head, partly over the scalp and into the ears, running past the temoral bone. Unfortunately, I have this as well. It too is on both sides of my neck, so I have both bilateral TN & bilateral ON. The Occipital pain will almost always trigger my TN pain due to the proximity of the nerves where they pass near the temporal bone and THIS is a nightmare for me.
Can I answer anything more specifically for you Christi?
Best wishes for a pain free days ahead!
