Ice and falls

yesterday I walked down to voice therapy.
We don't have much snow here, just compacted ice, which is very tricky to walk on. I slipped a couple of times but didn't go over, then with no reason I fell. It must have looked comic, as my legs shot out to my right, and I landed heavily on my left hand side.
Today I have huge bruises on my left elbow and hip, and curiously around where my boot comes up to, which illustrates the force with which I fell.
I ache, and sleeping last night was not easy, as I tend to lie on my left side.
I think I'll have to use some arnica or something before I go to bed tonight.
