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).
So when these muscles are tight they cause a tensional strain on the hip, which contributes to hip pain. The calves are often overlooked in hip pain, but they are among the strongest muscles of the body. Unreleased pressure in the calves pulls the hip bone out of balance in a similar tensional line with the hamstrings.
