What would you do in this situation?

I went to a friend's house on Thursday for an ole-fashioned playdate. Now, this friend of mine is a woman that I've known for around 8 years. We don't see each other that often, but our children are in the same age range. They adopted 3 children and two are 6 (Cecelia's age) and one is 5 (Bella's age). Consequently, the kids love getting together with them. She lives in Woodbury, which means that from Plymouth... it's a super-long-drive.

So, I drove all the way to her house and was just sitting down with a soda on her porch to talk (the kids were outside playing together) when something started happening. I felt my skin on my face, arms, and neck start to burn. It felt like my skin was literally burning off and I figured that a rash must have spread all over my face. As I sat there, I was thinking: "Do I say something? I wonder if I am completely red." I must have looked like a tomato or something.

Of course, I didn't really feel comfortable after having just sat down, to ask to see the bathroom. In addition, we don't see each other that often, so I wasn't all that comfortable in exclaiming that my skin was burning off. Also, this has never happened to me. I'm not prone to rashes and typically will have the sore-throat/stuffy nose symptoms when I'm allergic to something. I've never been the rash/fever type.

To top it all off... I have no idea what I might have had a reaction to! No pets... so could it have been something in the air?

I'm sitting there thinking to myself: "If this gets worse, I'm asking for benadryl."

After about 20 minutes of skin-crawling pain, it finally subsided a little and I went into the bathroom. My arms and neck/chest area was bright red. After a little while longer, it all went away and I didn't have any more problems.

I wonder if my flaming tomato skin was alarming to her.
