Question By: The symptoms of a dangerous spider bite in Australia can vary depending on the type of spider, but common signs often include local reactions such as pain, swelling, and redness at the bite site. More severe symptoms can also occur, particularly with venomous spiders like the Sydney funnel-web or Redback spider, which are among the most dangerous.
Local Symptoms
• Pain: This is the most immediate and noticeable symptom, which can range from mild to intense. In the case of a Redback spider, the pain typically starts within 20 minutes and may be severe.
• Redness and Swelling: The area around the bite will often become red, swollen, and inflamed. This reaction is common to most spider bites but may be more pronounced in venomous bites.
Systemic Symptoms
• Sweating: Profuse sweating is a common symptom, especially with a Redback spider bite. It may affect the entire body and be associated with nausea and dizziness.
• Nausea and Vomiting: Nausea, vomiting, or abdominal pain can occur, particularly with the Redback spider, which often leads to these gastrointestinal symptoms.
• Muscle Pain or Weakness: Muscle cramps or weakness, often felt in the limbs, may be a sign of a Sydney funnel-web bite, which can cause systemic effects like increased heart rate and high blood pressure.
• Chest Pain or Difficulty Breathing: This is more common in severe cases of a funnel-web spider bite, as the venom can affect the nervous system and breathing.
Severe Reactions
• Loss of Consciousness: In very rare cases, especially with a Sydney funnel-web, the venom can cause confusion, seizures, or even loss of consciousness.
• Allergic Reactions: Severe allergic reactions to spider bites can lead to anaphylaxis, which requires immediate medical attention.
If bitten by a dangerous spider, it's critical to seek immediate medical attention, especially if symptoms worsen or if the spider is identified as highly venomous. Visit https://www.flick.com.au/blog/dangerous-spiders-in-australian-homes/ to know more.
