Do I need crutches? Rolled Ankle?

My doctor checked out my xrays and said it was a severe sprain but thought since I'm walking on it that it's improving. I rolled it on the 5th of June, today's the 16th. It was my first time being at the doctors so I was kind of freaked out lol so I didn't tell him that it actually hurts MORE now. I haven't had swelling at all since I rolled it, probably because I walked it off and have been icing it which hasn't helped either. I rolled my left foot, pain is on the outer side of the foot ( Left side) on the inside (right) running up my shin and now my toes are beginning to really hurt too. It's become more and more painful to walk, should I get crutches?
