Unfortunately, dislocations come in many different forms and affect people differently. They range form a mild subluxation to full dislocation. I've had no end of shoulder issues over the years ending in surgury and all I can say is get it looked at. Climbing with shite shoudlers is more grief than it's worth, I ended up on the operating table.
Was there any loss of movement/range? Any feeling of insatbilty/weakness in ceratin positions? Could you get some one to isolate it (i.e. hand on top of the shoulder so you don't bring other muscles/joints into play) and put it through it's range of motion? Bit difficult to describe over the net.
On the plus side for you, if you are who I think you are, dislocations get rarer with age and the chance of re-occuring decreases as well.
(I think I've met you at Bear Rock and out in the peak).
