If you’re worried your son may have the staph infection, have your doctors do a blood test and look for the s.e.d. rate. That is a mechanism whereby they check for infections in the system.
A normal s.e.d. rate is between 1 and 10. I had the mrsa infection due to a past back surgery...my s.e.d. rate was 220.
Took alot of liquid antibiotics pumped through a pic line directly into my heart for 13 weeks, but thankfully they got it.
So, if the staph is your concern, please ask your doctor of that possibility.
Hope your son gets well.
