A groin muscle strain or pull is often associated with overstretching the muscle beyond its limits. Athletes and performers are usually more susceptible to pulling or straining muscles, but those who have limited or poor flexibility are also at risk. Symptoms often include swelling, inflammation, immobility and mild to extreme discomfort depending on the damage done to the tissue. If a groin muscle pull is suspected, discontinue any use or activity until these symptoms have subsided.
Swelling
Swelling often occurs immediately after a groin pull or strain. According to the American Council on Exercises "Personal Trainers Manual," swelling in muscle tissue occurs when the body increases blood flow to the damaged tissue in order to deliver more oxygen and nutrients to the area. As blood collects around the damage, swelling can be seen and felt where the tissue has been injured. The extra injection of nutrients and oxygen is needed to repair the damaged tissue. Typically the body shoots more blood to the damaged area than necessary, which is why it is recommended to ice the injury with a cold compress immediately after it occurs. This slows down the blood flow and thus reduces swelling.
Immobility
As swelling increases, inflammation and immobility of the surrounding muscle groups follow. The American College of Sports Medicine's "Resources for the Personal Trainer" says that the swelling creates more blood flow in the muscle, which can hinder its full range of motion. This is the body's way of protecting the muscle from further injury that may occur through normal movement or activity. It is recommended that groin strains or pulls be properly rested and that the legs be elevated to help with blood circulation.
Inflammation and Discomfort
Often times with swelling and immobility comes inflammation. Inflammation causes mild to extreme discomfort in the affected area because of increased blood flow. According to American Council on Exercises "Personal Trainers Manual," inflammation can cause throbbing and even muscle spasms. Even if the muscle is completely immobilized, pain can still be felt in the area. Over-the-counter pain relievers such as ibuprofen or acetaminophen can reduce the discomfort caused by swelling and inflammation. An article on sprains and strains by the Mayo Clinic warns individuals that if you cannot move the affected joint or find it difficult to walk more than four steps without significant pain, you should see a doctor.
