Should i get crutches i sprained my ankle i can walk as long as i don't bend it at all it hurts even like that its badly bruised and swollen what todo?

Not necessary: Although an ankle sprain may be swollen and painful, usually rest, icing and bracing may be suffice. Try a compression wrap or a simple ankle brace for 1-2 weeks. If pain and swelling gets worse, then see a doctor for referral, possible imaging studies to see if the injury is more serious than just a sprain. I hope this helps, if so, please vote or follow me. Thanks!

X-ray : You need to be sure this is only a sprain and not a fracture. Get an x-ray and if no fracture then a lace up brace, otherwise you need to see an orthopedic surgeon.

First: Thing to get is an x-ray to make sure there is no fracture. Rest, ice, compression and elevation will help. If hurts when bending the joint get it checked to make sure there is no complete rupture of ligaments.
