Hi there, I do martial arts and jammed my middle finger in sparring. There was immediate pain with swelling around the large knuckle and I couldn't make a fist. Now, about a month later, my finger is still sore and stiff, and I experience discomfort when trying to make a fist and pain when I try to bend my fingers backward to stretch. I'm concerned because I noticed what could be swelling around the tendon just behind the knuckle.
Should I be doing something for it, scheduling an appointment or resting it more than I am?
