There's an ointment on the market that is castor oil based that might be quite good for ligament pain like that. It's called Castiva. Whenever we used to sprain ankles in our family, my mother would prescribe a 'castor oil wrap' Putting castor oil in the ace bandage wrap would speed up the healing wonderfully. So this Castiva that my mom recently found is the stuff she now recommends as it is castor oil based. Good luck! You'll be back on the bike soon I'm sure!
