Your heart is hard at work pumping blood and nutrients throughout your body. You can sometimes hear it or even feel it as it pumps at a steady pace. The heart keeps an even, reliable rhythm that's controlled by your bodyâs own electrical system. When that system has issues, the rhythm changes. This is known as arrhythmia, which is a problem with the heart's rhythm.
What is a hip flexor strain? A hip flexor strain is an injury characterized by tearing of one or more of the hip flexor muscles and typically causes pain in the front of the hip or groin. The group of muscles at the front of the hip are called the hip flexors. The most commonly involved muscle in a hip flexor strain is the iliopsoas (figure 1). The iliopsoas muscle originates from the lower back and pelvis and inserts into the thigh bone (femur).
The second occurs when the deep hip flexor snaps over the front of the hip joint. Finally, tears of the cartilage, or labrum, around the hip socket can cause a snapping sensation. Strains of the muscles around the hip and pelvis can cause pain and spasm. The most common strains are groin pulls and hamstring strains.
