It can take time for a abcess to form .. You are reffering to Jack Bear correct??
Maldorh and I where the ones that first told him to go to the doc.. If you read back through his thread you will see that after he posted his pic my response post was celiutitis info . It looked like that's what he had to me, But I didn't want to make it worse by scaring the shit out of him . Sadly to say my thoughts where right and he said the doc looked at it and said cellulitis right away.... I am just happy for him that it all worked out !!!!
Now if yours is showing sings of infection symptoms ( red and hot to the touch at inject site , fever and so on) I will say the same thing I told Jack Bauer.. Go to the Doc now....
