Get an X-Ray, especially at your advanced age. I took a similar tumble and
wrote off the nagging pain for 6 months, with the help of a lot of gin.
When the clicking emanating from my shoulder did not go away,
I decided to see a Doc in the Box for help. Turns out it was broken, and my body made the correction by dropping my shoulder so the fractured ends didn't hit to cause any pain. But in the 6 months or so, the ends of the break grew knotty and misshapen. Ended up having some bone from my hip taken off and grafted onto the broken clavicle after the knotty ends had been cut back. Year later opened up again to remove the steel brackets from the graft. To this day my "fixed" shoulder is 3/8" shorter than the natural side. Go to get it checked out.
Or book a night at the Holdiay Inn Express.
