How do you treat a sprained thumb?

== == First make sure it's only a sprain. If there is any doubt about torn ligaments or broken bones you need to be seen by a doctor. However, if you can move it around, there is no "crackling" with movement, and the only symptom is that it's sore, then do the following:

Use ice the first 24 hours after a sprain, then heat to the area after that.

(Reason: ice reduces swelling and any bruising when you apply it right away. It will help cut down on pain as well. Then using heat will help improve circulation to the area and promote the healing process.)

Immobilize/Rest your thumb with a splint for a couple of days..no longer.

(Reason: give the sprained muscles, ligaments, tendons time to rest.

However, do not wear the splint longer than a couple of days or you

risk having the muscles, etc, get very stiff.)

It's easy to make a splint out of Popsicle sticks and tape. You can also buy

splints at the drugstore.

Finally, as the injury begins to heal, gently flex and extend your thumb to loosen it up. As it becomes less sore, exercise it more so you don't get a stiff thumb joint.

* IMPORTANT*

See your doctor immediately if your thumb becomes white and cold, or turns very dark. These are symptoms of a problem with the circulation and that is an emergency.
With a thumb injury there are a couple things to do to treat it. Alternating heat and ice to reduce swelling. Nsaids (like ibuprofen) also to help with pain and swelling. Also taping the thumb in such a way as to mimic the tendons of the thumb. The taping with give added strength and support to the thumb and reduce further injury. Be sure to tape it in, what is called, gross anatomical position. Basically act like you're holding a soda can and tape it in that position, if that makes any sense.
