If you've had trigger finger in the ring digit, you might be experiencing a minor form of it in the middle digit now. Morning stiffness, pain along the Palm side of the digit (particularly by where the finger joins the palm, difficulty making a full and tight fist, and grip strength weakness are all possible symptoms. You don't always have to have locking of the finger. Look up stenosing tenosynovitis.

You can try stretching exercises (try to use the other hand to hyperextended the affected fingers), oral antiinflammatories, less repetitive gripping, wearing gloves/padding while doing manual labor, etc. some people respond to hand therapy. If it's bothersome enough go see a hand surgeon (either plastic or orthopedic) for a cortisone injection. If you've exhausted all that, surgery is a curative option.

Good luck.
