Anterior ankle impingement

Has anyone has to deal with pain in the front of the ankle, right where your leg meets your foot. I was bouldering a few weeks back on some tall boulders and kept taking falls onto crash pads. I noticed at the end of the session that my “ankles” were hurting, right where your foot starts to bend at the ankle. That was about 3-4weeks ago and I still have a lot of discomfort there. Has anyone had to deal with this and if so did you have stretches and excercises that helped deal with the pain?
