Futsul

I like football and futsul.
I played futsul yesterday after a long break.
It was very very exciting!!

I injured hurted my back last October and went through an operation am operated in this April.
I keep to do go to rehabilitation seeions regularly to make it better. 

However, (don't start a sentence with "but") I can't move I think, because my muscle is weaker than before,
and my muscle was aching very much today...
