Last night, my mom had a weird looking bug bite on her arm. It was reddish purple, and kind of ugly looking. My mom couldnt remember if anything had bit/stung her.

This morning, she woke up and her tongue was swollen and she had a few hives on her leg and arm. She took a shower (I know from experience that if you're having an allergic reaction, warm showers/baths are not a good thing)

My dad (a nurse) wasnt sure if she was having an allergic reaction right away. He was thinking that her tongue was swollen because she'd bit it (she does that a lot sometimes)

I havent seen my mom yet today. She was taking her shower when I got up, and I went to take one before she was done. My dad had asked me thru the bathroom door if he thought he should take her to the ER, I told him to ask my aunt (another nurse) who might have more experience with it. She came over, looked and said take her to the Urgent Care up the street from here. (that's where they are now)

The only big allergy that I know my mom has is a bee sting allergy.

Does anyone know if you can be stung by a small bee and not know it?
