Shittiest was dislocating my shoulder last year (for the third time in 4 years). The other two times were from moshing, and awkwardly moving a box of merch for my friends band. The third time I was just skating a few blocks to the store, got hung up on a slappy, and my shoulder gave out when I fell. All the dislocations had made the ligament like slack rope, there was just nothing holding my arm into place. Had to do surgery, missed about a month and a half of work, couldn't skate for 6 months, it was fuckin' whack.
I definitely feel a lot better knowing I don't need to baby my arm anymore. But its also the injury that made me realize I'm starting to get older, and my body just can't take the same kind of abuse it used to.
