An ischial apophysis avulsion is an injury to the sitting bone where the hamstring muscle meets the bony protrusion of the sitting bone or ischial tuberosity. An avulsion is an injury in which movement or injury results in a violent and sudden contraction of the hamstring which pulls a piece of the sitting bone with it. This injury typically affects young athletes, aged 13 to 25 years. Symptoms include ischial tuberosity pain, swelling and pain in the thigh area, muscle spasms, and muscle weakness in the legs. To heal the injury, extended rest and massage are typically in order as well as stretching exercises and gait work.
With a roster of muscles ranging from the powerful glutes to the small and agile abductors, the hips control practically all your movements. Almost every endurance athlete overworks some hip muscles while underworking others, causing severe imbalances: Runners are infamous for having weak hip adductors—the muscles on the side of the hip that help you step laterally—while cyclists tend to have massive quads and tiny glutes.
How to: Start in a standing position with your feet hip-width apart. Bend your knees slightly, and sit your hips back into a slight squat position. Keep your arms lifted at shoulder height, with your elbows bent and facing the side of the room. Bring one foot up, rotate your hips, and place that foot down on the ground, diagonally behind your body. Pause, then return to starting position. That's one rep. Do eight reps on each side. Do three to four sets before moving on to the next move, resting for 30 seconds in between each set.
How to do it: Grip the barbell so you’re standing straight with the barbell at arm’s length in front of your thighs. Kick your left leg back so it’s just off the floor. Bend over so you’re hingeing at the hip while allowing only a slight bend in the right knee, and lower the barbell to the floor while keeping it close to your body. Pause at the bottom, then reverse the movement back up to the top. That’s one rep. Repeat this movement, alternating sides each time.
Here is how you do the hip rotation stretch: Sit on the floor with your knee out straight. Cross one leg over the other by placing your ankle on top of your knee (as if crossing your legs while sitting). Gently pull your knee across your body, and hold for five seconds. Then gently push the knee of the top leg away from you until a stretch is felt in your hip. Hold this position for five seconds, then slowly release. Repeat 10 times.

Of course, you know what it feels like to have a tight muscle. But tight hips aren't just uncomfortable—they can lead to all sorts of other aches and pains, especially in the lower back. "People focus on the hips and say their hips are tight, but we don't always think about the fact that the lower back connects to our legs at the hip," Charlee Atkins, C.S.C.S., instructor at Soul Annex in New York City and creator of Le Stretch class, tells SELF. Tight hip flexors make it harder for your pelvis to rotate properly, which can cause your lower back to overcompensate, "and this can be a setup for lower-back injury," Teo Mendez, M.D., an orthopedic surgeon at NY Orthopedics who focuses on operative and non-operative management of sports-related injuries, musculoskeletal injuries, and arthritis, tells SELF.
“Red flags” are signs or symptoms that something medically ominous may be going on. Red flags are not reliable, and their presence is not a diagnosis. When you have some red flags, it only indicates a need to look more closely. Sometimes red flags are missing there really is something serious going on… and sometimes they are a false alarm.18 Check off all that apply … hopefully none or few or only the least alarming of them!
The hip flexors are the muscles at the front of your hip. They’re responsible for several essential functions. Since they’re so often overlooked, we often forget to stretch them before exercising or engaging in rigorous activities. Tight hip flexors can also be a product of being sedentary. So, if you don’t lead an active lifestyle, or if you spend most of your day sitting at a desk, you’ll be susceptible to hip flexor tightness.

A physician should be consulted in those acute cases when the condition is accompanied by reddening, swelling or hyperthermia of joints, ongoing joint trouble or severe pain and/or are associated with neurological symptoms

Grade III (severe): A complete tear in your muscle that causes severe pain and swelling and you can't bear weight on that leg, making it difficult to walk. You've also lost more than 50 percent of your muscle function. These injuries are less common and may need surgery to repair the torn muscle. They can take several months or more to completely heal.
