i get jaw pain when i take my adhd meds from clenching my teeth.. i get botox for my unbelievably tight traps from my EDS and it makes a world of difference. you could try it, i know it can help people w TMJ. but it also will slim your face.. also maybe a muscle relaxant like flexeril could help relax your muscles if youre clenching. also clonidine is an ADHD medication i take as well, it lowers my blood pressure and helps me relax during the night but w POTS it can be tricky. lastly maybe you could try acupuncture, from an orthopedic acupuncturist. theyre not that expensive and orthopedic ones are very western and more modernized in their treatment. i think its worth trying a few times because it can make a world of difference for muscle pain especially

this might help me with stimming too
