What should you know about adductor pollicis brevis pain?

Adductor pollicis is in the hand and helps pull the thumb toward the palm. Adductor brevis is in the inner thigh and helps move the leg toward the body's midline. Pinch-related thumb pain and activity-related groin pain therefore need different assessments.

Pain near the base of the thumb may involve the adductor pollicis, but nearby joints, tendons, nerves and ligaments can produce similar discomfort. Symptoms may be noticed while pinching a key, opening a lid or gripping an object.

Pain high on the inner thigh or at the groin may involve the adductor brevis or another adductor muscle. It can follow a sudden change of direction, kicking, running or a gradual increase in training load. Hip joint problems can also present with groin pain, so the sore spot alone does not establish the cause.

Reduce the movement that clearly aggravates the area, but keep comfortable movement where possible. For thumb pain, temporarily limit forceful pinching and heavy gripping. For groin pain, scale back sprinting, kicking, deep side lunges and rapid direction changes.

A wrapped cold pack may help after a recent flare; protect the skin and stop if it causes numbness or irritation. Do not force a painful stretch or repeatedly test strength against sharp pain. If symptoms persist, recur or restrict daily activity, a clinician or physiotherapist can examine strength, range of motion, tenderness and the joints above and below the painful area.

Arrange prompt assessment after a significant injury if you cannot use the thumb, grip safely, bear weight or walk normally, or if there is marked swelling, bruising, deformity or rapidly worsening pain.

Seek urgent care for a cold, pale or blue thumb; new loss of sensation; severe weakness; or pain with spreading redness, warmth, fever or feeling acutely unwell. Sudden groin pain with a new lump, severe abdominal or testicular pain, or vomiting also needs urgent medical assessment.

Ask which structure appears to be painful, what movements are safe to continue, whether temporary support or activity changes would help, and which findings would prompt imaging or referral. Mention exactly where the pain starts, what action triggers it, whether it began suddenly, and any weakness, clicking, numbness, swelling or pain at rest.
