Thanks ktgirl and rufalina, Ds also got a lump under the injection site (so did DS1 with each needle) but this is different.. it almost looks like a ringworm?? but not as scaly..like a sort of wobbly circle right on top of the injection site with little raised dots/lumps about the size of a pin head..sounds weird doesn't it? He doesn't see the MCHN for another 6 weeks...not sure if i should wait it out or take him to the doctor...is there a number or info line i can call for advice on immunisations?
