Tick paralysis
Tick paralysis is a rare reaction to the bite of several different types of ticks that are found in North America and Australia. It is caused by the venom released from the female tick during feeding.
Symptoms usually start 4 to 7 days after a tick attaches to the body. Symptoms of tick paralysis include:
- Restlessness and irritability.
- Tingling, numbness, or loss of feeling (paresthesia) that starts in the hands or feet.
- An inability to move (paralysis) the hands or feet.
Removing the tick stops the release of the venom and reverses the paralysis.
What are the symptoms of tick paralysis?
The symptoms of tick paralysis are caused by the venom secreted from a female tick during feeding. Paralysis is the inability to move a part of your body.
Symptoms usually start 4 to 7 days after a tick attaches to your body. Symptoms of tick paralysis include:
- Tingling, numbness, or loss of feeling or movement that starts in your hands or feet.
- Trouble swallowing or talking.
- Double vision.
- Loss of movement in your face.
If the tick bite is on the head, symptoms of tick paralysis may include:
- Facial paralysis.
- Double vision.
- Difficulty swallowing or talking.
Paralysis as a result of a tick bite is a rare problem. Most cases occur in children. When these symptoms develop, contact your doctor immediately to arrange for care. Removing the tick may be all that is needed to stop the release of the venom and control the symptoms.
