ive been doing d for 5 years, when i first started it happened allll the time, at least once a week, and i was so used to it that i didnt even bother with it. now that ive switched clinics, it hadnt happened in a few years, except small ones that were caught way before anything major happened, just sore... this one hurts like hell and is swollen like no other. i cant bend my arm, because it happened to be right next to the bend in my arm!! i really do take for granted using both my arms lolill try alternating heat and cold, but i always thought that heat made blood run?
