Signs of tetanus in feet

Tetanus is a serious infection caused by a toxin that affects the nervous system. A puncture, cut, burn, crush injury, or wound contaminated with soil can provide an entry point, especially when the wound is deep or difficult to clean. Foot symptoms may include tightening, twitching, cramping, or spasms that spread beyond the original injury. Tetanus does not always begin with obvious skin changes, so increasing stiffness after an injury deserves attention.

Rinse a wound under clean running water, remove visible dirt without digging into the tissue, and cover it with a clean dressing. Do not wait for spasms before checking whether your tetanus vaccination is up to date. A clinician can assess the wound, vaccination history, and need for preventive treatment.

Seek urgent medical care for new muscle spasms, a stiff jaw, difficulty swallowing, breathing changes, severe whole-body stiffness, or rapidly worsening symptoms after a wound. Go to emergency care immediately if breathing is affected or spasms interfere with movement. A deep, dirty, or puncture wound also needs prompt assessment when vaccination details are uncertain.

Ask whether the wound needs further cleaning, whether your tetanus vaccination schedule is complete, and which changes should prompt emergency help. Tell the clinician when the injury happened, what caused it, and whether you have noticed cramping, twitching, jaw tightness, or swallowing difficulty.
