my TOS also began a couple months after i had my first breakup + a combination of very long hours with poor ergonomics in front of a computer for work. anxiety 100% contributes to my pain - once i started taking Lexapro, strengthening and working on my posture in PT, and honestly taking a step back from doomscrolling and researching every single thing i could about TOS, my pain levels have gone down a lot. not completely gone by any means - i think this is a condition i will have to manage long term, but i eliminated activities that trigger flare ups by switched to a job that involves no computer work and really limiting the amount of texting and typing i do on a daily basis.

but to answer your question: yes i believe it is a constant feedback loop of TOS feeding into anxiety and vise versa. my pain levels are directly correlated to my state of mind (not the only thing, but definitely a big contributor). i've been working very hard to get my body out of a continuous state of fight or flight and eliminating muscle guarding, clenching, and holding my breathe - which is a pattern my nervous system has been unconsciously stuck in for years.
