The “spasm” wich he experienced is real, i’ve got it aswell when i had seizures. Specially in arms and legs but mostly arms.
For legs i belive it was the vastus lateralis and rectus femoris muscle and that is if im not wrong where the arteries are located in the legs. Would first cramp up and then i felt like if my muscles would have a little dance party for themselfs.
My arms was mainly biceps and forarms, cramps and shaking often after heavy hours at work. My work is physical demanding im a surface treatment operator and heavy equipment mechanic.
Had also spasm in the neck, but that happened only after covid-19 and influenza. It was all the way from the lats to the trapezus and sternocleidomastoideus. That happened very rearly as it mainly came from after sickness.
But if it is related to ES, i belive so yes very much indeed! Neck,shoulder,back and breast muscle is in my eyes one big set off muscles so one muscle will affect the other one i guess. As my physical therapist said is that the spasm i experienced comes from compression and “sourness” and as most off us who goes untreated over a long period off time the muscle tissue would become extremely “sour” and stretched. For the legs however im not sure, but the main arterie will conect somehow to the internal jugularis ?
I belive that muscle tissue, vains, fat, skin and bone tissue that is under compression and is stretched over a long time will somehow “deform” and then it will take alot off time to get it in the neutral/natural position. For me this is self explained, because if you have component in your body that is oversized like a calcified bone or as for ES styloids. There is not the aivailable space for it for that amount off time it is like a well calculated and fitted part in a machine. If one part is to big, the other parts will perform badly and become stretched and broken over time. For comparisson it is the same with skin from the belly, it would take some time to get rid off loose skin after fat loss because it has been stretched and compressed fast and much over time.
To add to this my physical therapist mentioned last time we spoke that my neck is crooked, right after the “clothes hanger” or in another word C2. So that is interesting because C2 is located near the hyoid bone, and between the cheek bone, hyoid and the styloid ligament there is not the best space for something that can grow long as for my case 4,5 cm long calcified styloid ligament.
And T1 to C1 is a critical and brittle component in our neck and back area. It is a weak link in the chain.
