Thigh & Hip
The hip and thigh hold some of the most powerful muscles in running, but they're also prone to strains, stress fractures, and nerve-related conditions that are frequently misdiagnosed. Weakness or tightness here often contributes to injuries felt elsewhere in the body.
Hamstring Strains
A sudden pull, tear, or strain in the muscles at the back of the thigh, ranging from mild tightness to a sharp, rupture.
Hip Flexor Strain
Sharp or cramping pain at the front of the hip where the thigh meets the pelvis, often striking suddenly during a sprint or explosive movement.
Adductor (Groin) Strain
Sharp or aching pain along the inner thigh and groin that flares with sprinting caused by a tear in the adductor muscles.
Quadriceps Strain
Sudden sharp pain or tightness at the front of the thigh during sprinting or explosive effort, caused by a tear in one of the four quadriceps muscles.
Piriformis Syndrome
A deep aching pain in the middle of the buttock that can send shooting or tingling pain down the back of the leg, caused by the piriformis muscle compressing the sciatic nerve.
Femoral Neck Stress Fractures
A hairline crack in the narrow neck of the thigh bone just below the hip joint, causing deep groin or hip pain that requires immediate medical attention.
Greater Trochanteric Pain Syndrome
Persistent aching on the outer side of the hip that worsens with running caused by irritation of the gluteal tendons and bursa over the bony prominence of the hip.
Hip Labral Tears
Deep groin or hip pain that may come with a clicking, catching, or locking sensation in the hip joint, caused by a tear in the cartilage ring that lines the hip socket.
Snapping Hip Syndrome
An audible or felt snapping or popping sensation in the hip during movement, which can range from a completely harmless quirk to a painful condition.
