3 year old boy with serum sickness
My son took 10 days of amoxicillin for a cold and ear infection. On day 10 his knees swelled up so bad he couldn’t walk. The next day his hands swelled up too and a rash started moving all over his body.
Long story short, he got diagnosed with serum sickness. They did labs, urine sample, and X-rays with no findings.
Has anyone else’s kid had this? How long before it was completely gone? We are on day 10 and the swelling is gone and rash isn’t near as bad but still comes and goes.
Dr said he can’t take penicillin family ever again
