I stepped on what I'm assuming was a bee two days ago, after I automatically went ahead and took two Benadryl. My toe never swelled really bad, it just burned and has a red looking rash on it. Two days later, it still burns and has a red color to it. It actually looks like I burned it in a way. Is this a normal reaction? I have been stung before and the previous sting was much worse with the swelling
