Hand Therapy Hand Injury Therapy-question?

Hand injury therapy-question? - hand therapy

I have broken (or severely stretched?) Tissue on the inner surface (palm) with your hand.
I got my crutches around the house when he moved apparently pushed (or?) Too hard on the handlebars.

As a measure for the relief of the 1st, I have a bag of ice on the surface, then applying heat or cold and heat, can I apply?
With the current climate is so cold in the morning, then warm in the afternoon, I put my hand on the window.
Thanks for the suggestions of physiotherapy.
