i randomly had anxiety today and was experiencing a super tight chest and shortness of breath. i gave myself some space/alone time from my family and couldn’t bring myself to watch netflix or crochet (which are common habits of mine). i just laid in the fetal position in bed. all of a sudden, kinda below my left ribs started to twitch/spasm and released all of the tension - my anxiety went away. i tried googling to see if this was common and i don’t even know how i triggered the spasm. from the limited research i did, it might’ve been the muscle that connects the diaphragm to the upper abdomen. has anyone else experienced this? if so, do you know how to trigger the muscle spasm?
