What should you know about severe charley horse?

People use charley horse for a sudden painful tightening or a muscle bruise after impact. A spasm may make the muscle feel hard and shorten movement briefly. A contusion can cause tenderness, bruising, and pain when the muscle is pressed or contracted. The location matters: symptoms may affect the calf or thigh. Severe pain after a blow, a visible dent, or difficulty using the limb can indicate a more substantial injury.

Stop the activity and protect the area from another impact. For a fresh bruise, use a cold pack wrapped in cloth for short periods and keep the limb comfortable. Once a cramp eases, gentle movement can help restore normal length; stop if pain becomes sharp. Avoid aggressive stretching, heat directly on a fresh bruise, and deep massage early after an injury. Return to activity gradually when walking and light movement are comfortable.

Seek urgent care for rapidly increasing swelling, severe tightness, numbness, a cold or pale limb, inability to move normally, or pain that is out of proportion to the injury. Arrange a review if bruising spreads, walking remains difficult, or pain does not begin to improve. Emergency symptoms should be assessed without waiting for home measures to work.

Ask whether this is a spasm, contusion, or another injury; when to use cold or warmth; which movements are safe; and how to prevent a repeat episode.
