What happens if you get stung by a bee or wasp and you don't see a stinger and it swells?

If you get stung by a bee or wasp and don't see a stinger but experience swelling, it's possible that venom has still entered your body, causing a localized allergic reaction. Swelling is a common response to insect stings, even without a visible stinger, and may also indicate an allergic reaction. It's important to monitor the swelling and any other symptoms; if the swelling worsens or if you experience difficulty breathing, seek medical attention immediately. For minor reactions, applying a cold compress and taking antihistamines can help reduce swelling and discomfort.
