It took nearly 12 months, an emergency visit, and being lucky enough to get a Dr who listened before "the tests look normal, idk, do some stretches?" became "oh no, your arm's blood supply is compromised, we have to do surgery."
So glad I didn't listen to the other Drs, or I'd never have found I have the lucky combination of arterial and venous thoracic outlet syndrome. On the downside, they're going to cut my rib out, but it definitely taught me to trust my body when something seems wrong.
Thank you <3
