Re: U shaped Welt Rash
Although your baby had vaccination a couple of weeks ago, this could still be from the vaccines. You could take your baby in and have the doctor look at it, but they do not like to admit that vaccinations can cause any harm and will probably blame it on something else. Meanwhile, you can put some calendula salve or cream on the welt. You live in San Diego, so go to your local Henry's or Whole Foods and ask for something to help heal the welt.
