Random loss of blood supply to a finger joint

I seemed to lose blood from the top joint and it went white and numb for about 20 minutes while I was walking round the supermarket. It wasn't particularly cold, but this is the same joint I dislocated last year. It's happened once before but that was around a month after I injured it and I figured it was still healing on the inside. Should I be concerned?
