Question Trigger thumb

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?

Default Most Trigger Digits are not caused by Diabetes

Thank you for your question. In short, absent other issues that might make you worry about having diabetes such as: frequent urination, excessive thirst, extreme hunger,unusual weight loss, increased fatigue, irritability and blurry vision--the mere fact that you have a trigger digit probably does not warrant a special trip to your internist to check for diabetes.

Trigger digit is not all that uncommon, and can be successfully treated with a corticosteroid injection in the office. Most of the time, 1-2 injections work---but there is some data that suggests that the "injection approach" is less successful when diabetes is the cause.

In my practice I generally try 1-2 injections, even in patients with diabetes---because it can work. The only caveat is in patients with diabetes who have a problem with cortisone---increased blood sugars for example. In these cases I am more likely to recommend surgery earlier.
