Does anyone else relate uti symptons and emotional stress to hives??

A few weeks before my very first outbreak, I had uti symptons. I still dont know if it was a uti, but the symptons were similar.

Now, my hives are always triggered by anxiety, stress, nervousness etc. My hear rate goes up, I begen to get very hot and flushed and feel tingling, usually on my face. Then the itching begins and the hives appear.

What is the cause of this? Any info?

Thanks
