PMR Vitamin D and a Ganglion

[LifeLongNeedleWorker]

My current status, is 88 years old, 2.5 years into PMR and down to 5.5 dose of Prednisalone.

I have recently watched what I thought was a bony protrusion emerge as a bump on the knuckle of my right hand little finger. As it doesn't hurt I am still not worried about it. I showed it to my daughter who immediately said it must be a ganglion which had not entered my head.

We had a bit of a joke about the old method of bashing it with the family bible but since then I have ventured a little bit of research and see that it can be related to vitamin D and wonder if anyone else has experienced this or have any knowledge about this strange phenomenon.
