TIFU when I didn't listen to my body sending out painful distress signals because I live with chronic pain

I live with a disability that limits my ability to move parts of my body, impairs sensation, and causes chronic pain. Last night I kept being awakened by intense pain in the toes and main parts of my right foot. Typically, when I have these nights, I manipulate my toes and rub my foot until the pain returns to a manageable level and I return to sleep within a half an hour. Last night, I was frustratingly up four times groggily trying to move my toes and rub my foot and everytime I would finally find relief from the pain and return to sleep the pain would return within two hours. When morning finally came, I work up and removed my socks to put on a fresh pair when I found several lose elastic threads in my sock wrapping around my foot and my toes. Had I not tried so vigorously to relieve my pain I am not sure I would have maintained adequate circulation and feel like was in danger of losing some toes or part of my foot. It's entirely possible on my worst pain days I might have gone so far as to have not changed my socks and I would have spent even longer in a dangerous situation.

TL;DR -- I live with chronic pain and have limited mobility and impaired sensation in my foot. Because my brain is stupid and tired it tried desperately to ignore severe and persistent pain. I woke in the morning to discover broken elastic threads in my sock were basically creating a tourniquet and limiting circulation in parts of my foot and toes.
