Immediately take him to the hospital Emergency Room and find a specialist in infectious disease control.
This is way above Urgent Care abilities. MRSA is deadly.
I had a badly infected big toe 25 years ago ... had to have a chunk removed due to gangrene ...
This is SERIOUS ,, clean thoroughly with hydrogen peroxide , remove any dead skin , crusty mess and anything that looks bad ... find any general broad spectrum antibiotic capsule you may have (amoxicillin is good),, if you don’t have any ask the neighbors... break the capsule apart and put the powder directly into the wound.
If it looks like it’s responding you’ll be ok ,,, if there is any sign of necrosis or it doesn’t respond get to an ER.
Rita - I agree. This needs urgent care at the hospital where specialists in infection control can determine what is causing the infection. Minimally a culture needs to be taken and antibiotic sensitivity tests dome. You are right MRSA is nothing to dally with.
Perhaps the boy needs to be on intravenous antibiotics to get the medication into his system rapidly.
This is way above Urgent Care abilities. MRSA is deadly.
Enthusiastically seconded.
I agee! Please don’t wait!
Prayers continue for you all.
