My twin sister decided to open her mouth and show me the back of her throat(I have a sensitive stomach) well...she seems to have this white solid patch that wont remove when she tried whiping it offwith a Q Tip. She said it started off as a white ball then another came along and now it's this white patch...oh and it looked like she had some color in there i want to say green but it was such a quick glance.. I wasn't prepared for that.
