Rest it but, if problem continues, see doctor, as others wisely counsel.
It's a sensitive point to me. I hurt mine in a tournament and kept playing because I was doing well. "Play through the pain". This led to a long period where I'd rest it for 6 weeks, play, rest for 6 weeks, see a doctor, see a chiropractor, see a physical therapist, etc., etc., all the while being able to play less and less. I finally saw an orthopoedist and, 2 years after the injury, had surgery on my torn labrum and missed most of another year with rehab. Another 3 years to get my rating back to where it was.
So I lost a couple of years out of my disc golf life that I would have saved if I'd sought proper treatment earlier.
