Patient received Hib and polio vaccines on the left leg approximately three weeks prior to the visit. The nurse who administered the vaccines was described as rough, and there were concerns about her technique, including the placement of alcohol and the bandage, as well as the depth of the injection. Blood and vaccine fluid were observed at the site, and the bandage was placed away from the area where blood was coming out. Dad states, "the nurse did not seem in her right state of mind." No fever was reported after the vaccine. No itching at the injection site was observed. Following the vaccination, mom states patient began walking with her left foot turned outward and her right foot facing forward. This change in gait was noticed immediately after the vaccines and has persisted, with the left foot now turning outward even more, and an increase in falls has been observed since the vaccination. This walking pattern was not present before the vaccine. The area of the injection developed a lump under the skin, initially the size of a small grape, which has since decreased to the size of a lemon seed. The lump was visible and palpable, and the area was swollen but not bruised. The site was tender to touch, causing discomfort but not severe pain; patient would pull away when the area was touched but did not cry or react as if in significant pain. Mom did not feel administration of tylenol or ibuprofen was necessary. Mom also reports red spots appeared and disappeared in different locations on patient's body during the week following the vaccine, which was unusual for her. These rashes were not associated with itching. These spots have since resolved.
