What should you know about semitendinosus bursitis?

A bursa cushions movement between soft tissues and nearby structures. Repeated kneeling, running, friction, altered walking, or a nearby tendon problem can irritate it. Pain is often focused near the inner knee or lower back of the thigh and may worsen with bending, stairs, or pressure. Swelling can be subtle, and similar symptoms can come from tendon, joint, or nerve problems, so location and examination matter. A clinician may assess movement and consider imaging if the diagnosis is unclear.

Reduce the activity that repeatedly compresses or rubs the area, while keeping gentle movement within comfort. A cold pack wrapped in fabric may help for short periods. Footwear, training volume, hip and knee strength, and movement technique may need review. A clinician may discuss anti-inflammatory medication when suitable for you. Persistent swelling or fluid may lead to consideration of aspiration; an injection is a separate decision based on the diagnosis and surrounding structures.

Arrange prompt medical assessment for increasing warmth, redness, marked swelling, fever, or feeling unwell, because infection needs different treatment. Seek urgent help for sudden inability to bear weight, severe injury, rapidly enlarging swelling, or a cold or numb foot. If symptoms persist despite reducing aggravating activity, assessment can distinguish bursal irritation from a tendon or joint condition.

Ask which structure is inflamed, whether fluid is present, and whether an infection or joint problem needs exclusion. Discuss safe activity, medication interactions, the role of physiotherapy, and when aspiration or injection would be considered.
