We went to the ER and once the Attending Physician saw his foot, he said he would most likely admit Dear Son to the hospital. They started an IV, drew some blood for labs and did a blood culture. He was admitted that evening and started on IV antibiotics.
On Sunday, they continued the IV antibiotics and diagnosed him with Cellulitis, a somewhat common bacterial infection that typically presents through an open cut however Dear Son didn't have any. (All photos were taken on Sunday.)
By the afternoon, around 3:30 p.m. the foot had started to look better however at 5:30 p.m., just two hours later, the redness had spread over his ankle, the bruising had expanded and the swelling had increased. I contacted the Pediatric Attending and they consulted with the Orthopedic Surgeon. The Peds Group started a second IV antibiotic however the foot never improved.
