Thanks for posting,
From your description it will seem obvious to conclude that the intake of amoxicillin
is likely associated with the leg pain (plus the example that you quoted related to the other parent). Now, leg pain is not a known side effect of amoxicillin and personally I have never come across or head of any. The common side effect of amoxicillin is stomach flu
and/or yeast infection and others may follow mainly gut disorders. The amoxicillin given to your son was clearly for an infection which might not have been under control yet, given that your son is still presenting with a low grade fever
. It will be wise to take him back to the doctor in any case.
Your son include the other parent's child might have developed a rare and unknown side effect of amoxicillin which still be under investigation by researchers. There will be a need to change antibiotics or include analgesic
with both antipyrectic and pain killer properties so as to control both the fever and the pain.
Hope this helps
