Trigger Finger and Trigger Thumb, medically termed Stenosing Tenosynovitis, are common hand conditions. This condition occurs when the tendons in the thumb and fingers do not glide smoothly. Tendons are strong tissues that connect our muscles to our bones. Trigger Finger and Trigger Thumb causes the tendons to catch or get stuck when the fingers or thumb bend. This condition makes it difficult to straighten the fingers and thumb back out. It can also cause pain, discomfort, and swelling. Trigger Finger can occur in one or more fingers or the thumb at the same time, or it may occur in different fingers with or without thumb involvement at different times.
