Top of my ankle hurts

Options
In Jan. I started having pain on the top of my foot I ignored it as it steadly got worse finially in March I went to my Dr. she said I had sprained my ankle and everytime I go back to Zumba I just make it worse. Well here I am in July and currently by the end of the day the top of ankle were my leg and foot meet is sore its not painful it just feels bruised. I have been staying away from zumba cause Im scared Im gona sprain it agian. Zumba is the first exercise ive found that I enjoy and it doesn't feel like a chore I really dont want to give it up. What do you all think is causing this discomfort?
