Friday night at 10:30pm - I had already been to a walk-in clinic around 4pm. The doctor was very confused and even googled my symptoms - Totally comforting. I had already known from the night before that I was having an allergic reaction. He couldn't seem to understand that I didn't hit my hand on anything. At 10:30 I went to the emergency at Mount Sinia. They agreed that it was a (strange) allergic and decided to drain it.
