When a venomous snake bites you, it injects a complex mixture of proteins and enzymes known as venom into your skin or muscle. Because these substances are poisonous, they quickly travel through your bloodstream or lymphatic system—the network of vessels that helps your body fight infection—and start interfering with how your heart, nerves, and blood cells work.
The condition is considered a medical emergency because the venom can rapidly spread throughout your body, leading to serious internal damage. It primarily affects the site of the bite, but it can also cause systemic effects, meaning it impacts your entire body including your ability to breathe or clot blood properly.
Common Symptoms
- Severe pain, swelling, and bruising at the location of the bite.
- Puncture marks or fang marks on the skin.
- Numbness or a tingling "pins and needles" sensation around the mouth or limbs.
- Difficulty breathing or swallowing.
- Nausea, vomiting, or blurry vision.
- Weakness or paralysis of the muscles.
