Trigger thumb

[Ammon]

About 6 months ago, my left thumb developed a 'catch' when extending or flexing. I looked it up, talked with Dr. Mom, and discovered this is a 'trigger finger or thumb'.

The 'catching' has stopped, but it's painful, won't bend as far, and now there's a nodule on the palm side at the base of the thumb. I watched the video on this site and sure enough, it seems as the problem will require a steroid injection and possibly surgery.

With a family history of diabetes, while I haven't been diagnosed myself, should I consult with my primary care physician for a diabetes test prior to seeing a hand specialist?

Thanks!!
