Hello cherrygash;

I am a 10-year ptsd patient (since I was 28). Currently on Sipralexa, Sinequan, and TRT. In the early years I encountered occasional full body cramps/lockups and paralysis; and I suffered 30 heart cramps a day for 4 years without exception. Sometimes lockups with 'automatic' body functions like breathing, even when asleep (I woke up choking and not knowing/being able to breathe). I also had 30 'lockups' a day for 4 years when 'swallowing saliva' failed, resulting in a 'waterboarding' style of torture. This condition went away as later years progressed, and when the disease and/or my body 'evolved', some cramping came back, however, only in extremities (hand and feet, bizarely favoring the right (dominant) foot and hand. This is the current situation.

To answer your question, and from the top of my mind:

*I am able to do light work again. However, stress and workstress aggrevates or provokes cramps. When this happens, I isolate myself completely in a bathroom to avoid any external input from the surroundings. I also do not move, or I lie down.
*avoid crowded situations, in any sence of that word.
*I try twitching some muscles, preferably chest.
*I try to put my hands (fingers) in an opposite way than the cramping, usually by pressing against an object (a wall)
*concentrating on breathing, a technique that works for some, makes it worse for me.
*I try to get my mind to do other things. Like, counting backwards from 100. Unlike counting forwards, this keeps your mind more 'busy'.
*if available, drink water. Preferably cold. As much as possible.
*Giving your mind some 'inputs' may work. I try touching objects with the non-affected muscles to distort myself from the cramping. I.e, keep retouching a hot or icecold heating sink in that bathroom, but not with the affected muscle. I typically use a bare knee.
*Fresh air.
*Coldness. I.e, cold showers, or circling the deep freeze compartment in your warehouse (if you happen to be there), open a window,...
*forced coughing or throwing up to deter the body from the cramps.
*self-paining. I have hit my hands against the wall, gently and repeatedly, for years, to deter from the situation. The repetitive movement also distracts the mind. Be careful not to make scars. NOT for everyone, but worked for years for me. Some courses I took in anti-anx. suggested an automotoric action like tapping your finger repeatedly. It was much less efficient.
*forced reading, to distract. TV sometimes works, so do video games.
*excessive amounts of alcohol. This type of relexant, however, will weaken you afterwards. NOT for everyone. Be safe, don't drive.
*any type of benzodiazepine. I always carry lorazepam and unitranxene. Lorazepam works best. Do not operate heavy machinery or drive after.
*no coffee or stimulants, ever! Give it up.
*Being in a 'safe place' (home) will make you improve faster.
*Weed helps for some. Tried it for a year, didn't work. (I can smoke legally in my country; do not aggrevate any health issues by adding legal ones!)
*yoga/meditation helps some, but did nothing for me.
*massages help some, but did nothing for me.
*rest as much as possible on any given moment.
*relaxing music.
*psycologists and psychiatrics did nothing for me. Except take my money and waste my time.

Feel free to contact me if you have questions, and take care.
