My solution is simple and has been perfect for me. After difficult child asks me the 349th stupid question while I am trying to relax and after he does the 29th stupid thing I take the rest of the day to be oblivious and unconcerned. He asks me question # 350 and I say "go ask your Dad, Mom is off today." Just that simple act is so freeing. Even if the chaos stays I still can tune it out and be mostly left alone.
I do the neck tension/headache/teeth grinding. I think I may have just started some spasms in my tummy. No irritable bowel diagnosis as it happens once a month or so. Reminds me of labor pains, somewhere in the area of 5 to 7 centimeters dialated without an epidural. (I am an authority in that too)
About the neck issue, it really did almost cripple me with pain. Of course reducing stress is a biggie. lol
Other tricks that can be done easily enough
1. Good pillow. I sometimes get a new cheap pillow every month or two. I have noticed if my pillow is just a little off the perfect fluff I wake up in pain. I am a combo of side belly sleeper.
2. Drink plenty of water. The more hydrated I stay the less aches in general I get.
3. A nice soak in the bath with candles, incense, music the whole nine yards. Seems like a lot of work and some days I am too burnt to want to be bothered with it and I have to force myself to. 20 minutes later and I feel like a new woman. The freedom to think clearly in peace and quiet helps quiet my mind and ease what stress I can by processing the days events.
4. Horse liniment is my miracle cure. It's a lot like ben gay or icy hot but super mega strong. Has a minty smell that will melt off your nose but oh my goodness the way it soaks in and eases the tightness. I used to almost bathe my neck in it and it was the only thing that helped, even more than muscle relaxers which it helped me get off of. You can order it online or get it at feed stores. It does not need a prescription it's got menthol and a few other things. Comes in liquid or in a gel. Gel smells a bit better and is easier to put on. It gets your skin hot and cool tingly but not burning.
That, a couple tylenol and a glass of water before a nights sleep cured me. I used to have all day pain several days a week. I got back on track and haven't used anything in over 6 months. It just took a few weeks to slowly ease the knots out.
You can also use a steamy towel to get the liniment to soak in deep. it's pure bliss after being in agony. Tons of old timers use this folk remedy, it is perfectly safe. It's original purpose is for race horses. Those animals are abused, forced to do extreme exercise that damages their bodies and this stuff keeps them in tip top shape. Works for all sorts of aches and pains.
Pain has a way of eroding at the mind. The world seems so much brighter when you finally just feel normal again.
I hope with all my might you get there.
