Itchy bumps on face

I have been oil pulling for 5 days now. I have noticed 2 things and was wondering if this was normal. For one my gums feel more sensitive since starting...the first day it was really sensitive in one area and is now a little sensitive but is getting better. I'm thinking maybe there was an infection around that tooth that was super sensitive. Anyone have this happen to them??

The other thing is I've gotten two itchy bumps that have come up on my face. One happened yesterday. My face was really itch on the left side of my face and I felt a bump coming up, almost like a small bug bite. I looked in the mirror after a few hours and it was gone. Then it happened again today, this time around my mouth area. I just looked in the mirror and it's gone! I was sure these would be pimples or something but they have disappeared. Haven't had this happen before and think it could be from the oil pulling??? hmmm...any ideas?? Thanx...melissa Tweet
