Pain in my toe? What is the treatment?

I had this problem since three months ago when i was working out. Now, whenever I jump i felt a sudden jolt in my toe. My toe did not turn blue, swollen, red....etc etc. It looks normal. I can't bend my toe too much compare to my other toe.

My friend told me that i should use some ice to relieve it and wrap it with hot damp towel when I sleep. Is this true?
