Tuesday of last week, stood up quickly and slammed my temporal bone onto steel bracket supporting weight lifting machine. Next day moderate pain right side of head with swelling internally, no outward sign of injury. Pain persists, sometimes sharp pain side of head and face, hurts to open jaw as in eating, talking or just a yawn. I can feel swelling inside of temporal region. Some confusion minimal, Fallon and dropping things more than usual, temporary loss of peripheral vision. I keep hoping it will heal, but each day it is the same or worse...a bad day head feels heavy, pressure like, very mild headache. I am 62, healthy, do mixed martial arts, learning Spanish and my career is in muscle therapy. I do not want to make a fuss over this, but am increasingly concerned that something is wrong. Should I make the dreaded trip to an ER.
