Absolutely ice it, and take some ibuprofen.

The theory being that it is swollen, and wants to swell up even more. This swelling causes blood vessels to burst, causing even more swelling, and lengthing the time to heal.

Icing it reduces the swelling, and thus the collatoral damage. Ibuprofen also reduces swelling, but has certain risks (read the label, please).

Find a nice doc and/or sports medicine clinic and get them to check it out further.

Cheers
