Uh, I really dislike the CD & T Vaccine! I even went and got the Essentials brand that everyone raves doesn't leave lumps. Well it doesn't leave lumps right away.... they show up a few weeks later. I give vaccines in the air pit area or shoulder area. (Yes , I know shoulder area is not ideal but sometimes it's the only place I can find loose skin.) Anyways, I have one kid here who never lumped anywhere. Not even a hint of the vaccine site. Then I have one who lumped at the shoulder. But not a normal hard little bump. It's huge. Like Large Marshmallow size. It's not hard, it's kinda squishy. It's been 2-3 weeks since the shot and I just started noticing the lump about a week ago. Doesn't seem to be getting any smaller, if anything bigger I'm wondering if I should try to use a needle to draw out any fluid? I'm REALLY worried about it rupturing and becoming a scar. I'm certain it's in the same area I gave he vaccine because I write down where I vaccinate. Although it seems just a little farther forward but I think it's because of all the swelling. (This is kid like 13 lbs so a Large marshmallow sized lump seems really big .) THEN I get an email from someone who recently got a kid from me. He was vaccinated in the arm pit and they are having the same problem. A large visible lump that feels like it has fluid in it. He did not have ANY lumps or bumps when he left here almost 3 weeks ago. I clean the area well with rubbing alcohol, always use new needles/syringes. I know lumps happen but I have never had lumps this big. These are REALLY big! Is this normal? The only bumps I have gotten have been quarter to dime sized hard knots that eventually go away. Do I just leave them? Try to draw out fluid? Thanks!
