How to treat a severly jammed finger?

taping them together for a few days is a good idea, apply ice for twenty minutes (no longer) every couple of hours, take Ibuprofen for the antiinflammatory benefits, and keep your hand elevated above your heart as much as you can. After three or four days try taking the tape off and gently flexing the fingers, if there is still great pain with movement, time to see a doctor for an xray.
