That area has given me a lot of grief. My wrist/thumb area would get hot to the touch when it was painful. I found out years ago that Aspercream helped, along with ice packs. You might ask your Dr for a script for Voltatian Gel. My right wrist has been less painful lately because something in the joint has fused.

Cherish your yesterdays,
Dream your tomorrows,
But live your todays.
Do the very best you can
leave the rest to God.
God Bless,
