Overview

Muscle Strain
A muscle strain is an injury in which a muscle or tendon is stretched or torn. It commonly occurs during sports, physical work, lifting, or sudden movements and may cause pain, tenderness, swelling, weakness, or difficulty moving the affected area. Strains can range from mild overstretching to partial or complete tearing of muscle or tendon tissue.
Lichen Planus
Lichen planus is an inflammatory condition that can affect the skin, mouth, nails, scalp, or genital areas. It often causes small, itchy, or painful lesions that may appear suddenly or develop gradually. The condition is not contagious and may persist for months or longer. The appearance of lichen planus varies depending on the body area involved. Skin lesions are often purplish, flat-topped, and intensely itchy, while lesions inside the mouth may appear as white lines or patches and can sometimes be painful. Nail, scalp, or genital involvement can require additional assessment. Symptoms may improve over time but can recur.

Diagnosis

Muscle Strain
Diagnosis is usually based on the history of injury, symptoms, and physical examination. The clinician assesses pain, swelling, tenderness, strength, range of motion, and the circumstances in which the injury occurred. Imaging is not always necessary for a straightforward strain but may be used when a severe tear, fracture, tendon injury, or another condition is suspected. Ultrasound or MRI can help evaluate soft-tissue damage in selected cases.
Lichen Planus
Diagnosis is based on the appearance and location of the lesions and the medical history. A healthcare professional may examine the skin, mouth, nails, or other affected areas. A skin biopsy may be performed when the diagnosis is uncertain or another condition needs to be excluded. A clinician may inspect the distribution, color, shape, and surface of lesions and ask about medications and associated symptoms. Oral lesions may require examination of the gums, cheeks, tongue, and other mucosal surfaces. Biopsy findings can support the diagnosis when clinical features are atypical.

Prevention

Muscle Strain
Gradual conditioning, appropriate warm-up, adequate recovery, and regular flexibility and strengthening exercises can reduce the risk of muscle strains. Use proper technique during sports, lifting, and physical work, and increase training intensity gradually rather than making sudden changes. Avoid strenuous activity when muscles are significantly fatigued or already injured. Returning to full activity should be gradual after an injury and guided by symptoms and appropriate medical advice.
Lichen Planus
There is no guaranteed way to prevent lichen planus because its exact cause is uncertain. Avoiding known triggers or medicines that have previously caused reactions may reduce recurrence in some people. Regular dental care and avoidance of irritating oral products can help when the mouth is affected. Prevention is mainly focused on reducing known aggravating factors because the underlying cause is uncertain. People who develop lichenoid reactions after a medication should discuss alternatives with their healthcare professional rather than stopping prescribed treatment independently. Gentle skin and oral care can reduce irritation in affected areas.

Risk Factors

Muscle Strain
Risk increases with intense or sudden physical activity, inadequate conditioning, muscle fatigue, previous muscle injury, poor flexibility, and sudden increases in training intensity. Repetitive occupational activities and sports involving sprinting, jumping, or rapid changes in direction can also increase risk. Insufficient recovery between demanding activities may contribute to fatigue and reduced muscle control.
Lichen Planus
Risk factors for lichen planus may include certain medications, hepatitis C infection, immune-system abnormalities, and other triggers. It can occur at any age but is more common in adults. Some people may also develop the condition after exposure to specific substances or treatments. Some people with lichen planus have associated autoimmune or inflammatory conditions. Certain medicines can produce lichenoid reactions, and hepatitis C has been associated with the condition in some populations. Oral disease may be influenced by local irritation, dental materials, tobacco exposure, or other factors, although these associations do not mean that they cause every case.
