Hi, i was wondering about your daughter. We are currenly going thru a similar situation with my daughter, monthly recurring infections, rash,red eyed, high fevers and her blood work is all messed up. Out of the labs that were ordered, 13 came back abnormal. Her pediatrician is send us to an infectious disease specialist and thought maybe i would share this thought with you. I looked up kawasaki and it sound similar to what my daughter has as well. I would suggest if this continues, get her to a specialist who knows more about these types of illnesses. Good luck and i hope your daughter is feeling better.
Has she been swimming before the first infection' I have known children who react the the chloride in the water, you say she went swimming again and the symptoms are back ..the lump could be a lymph node.It may be a good idea to take her back to the doctor for another check up ..good luck
