Ankle pain

I'm 15 and in highschool soccer, maybe two practices a week my ankles will begin to hurt. It's wierd because they only hurt when I'm not running, if im sprinting the pain goes away.

I was wondering if anyone else has had this problem and what I should do about it.

You may have an minor ankle sprain.

There are three major classifications of ankle sprains. The most common and mildest type of sprain is a first-degree sprain in which the ligaments are stretched with minimal pain and swelling. In cases of a first-degree sprain the ankle ligaments are stretched without ripping the collagen fibers which make up the essence of the ankle. Second-degree sprains involve the actual tearing of the ligaments and fibers without total rupture. There tends to be more bleeding involved in these sprains because of the damage done to the torn tissue. Third-degree sprains require a complete rupturing of the ligaments and can involve surgery. These sprains tend to require a long period of rehabilitation. Third-degree sprains can include symptoms such as an ankle that 'pops' in and out. Also, in especially severe cases, the ankle can look twisted and deformed. These third-degree sprains tend to require no weight be put on the ankle; discoloration can also occur. With these sprains, the ankle may need to be put in a cast for as long as several months, but surgery is rarely necessary. When surgery is called for doctors usually want to repair a tendon—or reconstruct an ankle ligament.
