First order of recovery is often ibuprofen. 800 mg in the am and 800 in the eve for two days, then 600 mg in the am and 600 in the evening for 2 days, then 400/400, 200/200.
R.I.C.E. isn't exactly the best method. From having gone through PT for issues with my ankle they would massage the injury after a bit of heat. Soft tissue work is best. Also after some time blood flow restriction exercise did wonders. Basically they would wrap my ankle super tight with something called a voodoo band, but you can use a bike inner-tube. Wrap it while maintaining a neutral position, and wrap it pretty much as tight as possible. Then do roughly 10-20 squats, and quickly unwrap it. This flushes out inflammation, then lets new blood rush into the area to promote healing. Do a few sets of this, then ice it down for 10 minutes. Do this for a few weeks and it should help.
I'm far from an expert, I've just been going to PT a lot for various injuries over the course of many years. The above is just some of what was done for me when I suffered a pretty bad rolled ankle.
