Many times we feel as if we are unable to extend the finger by itself, or we cannot bend, once the finger is fully straight. This may be associated with pain at the base of the finger or thumb. Although any finger can be involved, the ring and middle fingers are more commonly involved, and the thumb is also involved often. When we feel the finger at its base, a nodular swelling is also felt. If you have such a problem, then the possibility is that you may be suffering from an entity hand surgeons call" trigger finger. Many patients also come and just report pain, or a snapping of the finger when straightening it.
Although anyone in the adult age group can be affected, this is more commonly found to occur in patients with diabetes, hypothyroidism, and other systemic illnesses.
It can present as either pain with a nodule in the palm, or with snapping of the finger on movement, or inability to either flex or extend the finger.
