Gum biopsy

So, I went for a gum biopsy today. I have a little hole in my gum. I will get the results in 2 weeks. Pray y'all that it isn't anything serious. The spot they took was there for almost a month. It's been 5 hours and no pain or discomfort. Only weird thing that happen was when he numbed the area, my heart started acting weird and beating fast. It last a couple mintues and then I was fine. Anyone ever had a gum biopsy?
