The most common cause for a hip flexor injury is acute trauma. On the golf course, this can happen when swinging a golf club and hitting the ground, a tree or a rock and having the club suddenly stop. This injury can also happen when attempting to compensate for Achilles' tendonitis, plantar fasciitis, weak abdominal muscles, or weak calf muscles, especially when walking long distances on a golf course.
The main symptom is pain at the front of the hip that will increase when moving the hip. There also may be apparent swelling depending on the severity.
To check for a hip flexor injury, bring your knee on your injured leg up toward your chest while standing, then have someone push down on the leg while you resist. If this results in pain in the front of your hip, then a hip flexor injury is confirmed.
Treatment usually involves rest and icing down the area. Careful stretching of the muscles for 30 seconds at a time can also help speed healing. In severe cases that involve the muscles being torn, a doctor may choose to repair it with a surgical procedure.
Warming up and stretching the hip muscles before each round of golf will reduce the chances for a hip flexor injury. Also, making sure you are fully recovered from Achilles' tendonitis or plantar fasciitis also will help avoid a hip flexor injury, as well as strengthening abdominal muscles and calf muscles with exercise.
