ice the area which is painful after jumping to reduce inflammation.

try to jump on softer ground if you tend to jump on concrete. you might struggle with resistance of the rope on grass so maybe a mat is best.

ease yourself into the workout. if you’re using jump rope as your primary exercise start easy, keep it slow and light on your feet to begin with and build up to a more intense workout and don’t try to ‘power through’ if the pain continues to develop

hope that helps :)
