Can't Pinch with Thumb?

The inability to pinch the thumb and index finger together indicates entrapment of the anterior interosseous nerve

in the elbow. This nerve entrapment often occurs between the two heads of the pronator muscle due to muscle growth or inflammation in the muscle. You should see a physician if this condition arises.

What will happens if a trigger finger is not treated?

In most cases, trigger finger is a nuisance rather than a serious condition. However, if it is not treated, the affected finger or thumb may become permanently stuck in a bent position or, less commonly, in a straightened position. This can make carrying out everyday tasks difficult.

Why cant I move my thumb without it hurting?

If you cannot move your thumb, or if it appears crooked after an injury, you should also seek emergency care. If your symptoms are recurrent pain in your joints, knuckles, and wrist, you may have an underlying condition such as carpal tunnel syndrome or basal joint arthritis.
