Thigh Groin Muscle Pain can be caused by muscle strain, fasciitis, or joint issues. Appropriate treatment methods, such as rest, cold or hot compresses, medication, or medical consultation when necessary, should be selected based on the cause of the pain. Identifying the cause of the pain is crucial. Preliminary judgment can be made by observing the tender area, the duration of symptoms, and changes in pain after activity, followed by targeted measures. 1) Muscle Strain or Overexertion: Prolonged vigorous exercise or improper exercise postures may lead to muscle strain, causing thigh groin muscle pain. In such cases, it is recommended to immediately stop vigorous activities and try to keep the affected area relaxed. Cold compresses can be used during the acute phase to relieve swelling and pain, and can be switched to hot compresses after 24 hours to promote blood circulation. Avoid resuming high-intensity exercise too early, and gradually incorporate gentle stretching and rehabilitation exercises. 2) Fascia Inflammation or Hamstring Tightness: Prolonged sitting or poor posture (such as long periods of squatting) may cause fasciitis or overly tight hamstrings, manifesting as local soreness or even tenderness. Stretching exercises can help, such as slowly touching your toes with your hands to improve the flexibility of the ligaments on the back of the thighs. Massaging the painful area can alleviate muscle tension. If symptoms persist after self-adjustment, it is recommended to visit a hospital for physical therapy or rehabilitation treatment. 3) Joint Problems or Other Complex Causes: If thigh groin pain is accompanied by knee stiffness, joint redness, swelling, or effusion, it may involve more complex conditions such as meniscus injuries or arthritis. In such cases, consulting a doctor as soon as possible is necessary, and imaging tests (such as X-rays or MRIs) may be used to screen for specific causes. Treatment options include anti-inflammatory medications (such as ibuprofen), hyaluronic acid sodium injections to relieve joint friction, and, in severe cases, surgical repair or joint replacement may be required. Thigh groin muscle pain can have multiple causes. If it is only mild discomfort, rest, stretching, and daily adjustments can usually provide relief. However, if the pain persists or affects daily life, it is recommended to seek medical attention as soon as possible to rule out serious conditions and obtain professional treatment plans.
