My son has a ruptured spleen. was sent home from er. what are some side effects while healing like maybe chills etc.?

Watch for bleeding: In children every effort will be made to save the spleen , to avoid the future life threatening infections of pnemococcus, meningococcous .Acts as filter of damaged rbc , & vital immunological roll. Need to watch rebleeding, dizziness , rapid pulse, looking pale less common infection, yes chills follow doctor instruction , any doubt take back to er to prevent life threatening re-bleed.
