When pulleys become too tight or the tendon becomes enlarged this can result in the tendon becoming stuck. If the tendon cannot glide freely, trigger finger occurs. Trigger Finger is a condition that at best is a mild irritation. At worst can cause severe pain and limitation of the fingers or thumb.
Symptoms associated with trigger finger or thumb include pain, tenderness, popping, locking or inability to fully flex or extend fingers and thumb.
