-- Posted by J3SSiiCA at 4:58 am on Nov. 20, 2008 3 or 4 years ago i had my TB injection at school and the day after i went swimming and it reacted. Only by making a bigger sorer scar, i didnt think anything of it. Ive just looked and its quite a big lump about the size of 2 of my thumb nails. When i press down on it its feels really strange and like as though its goey inside    you dont think its serious do you? -- Posted by callmeprincess at 4:59 am on Nov. 20, 2008 ask a doctor -- Posted by SimbaGrrl at 5:02 am on Nov. 20, 2008 Phone up the doc and ask... -- Posted by hi sarah at 5:07 am on Nov. 20, 2008 doctor -- Posted by MizzBre2Cute at 5:18 am on Nov. 20, 2008 Go to the doctor
