Severe case of strep throat

MY 21 year old daughter was given a jar of collodial silver to gargle and take and 2 days worth of oregano oil for strep throat. Didn't help. She went to Urgent Care and they gave her a penicillin shot and a tetanus shot for a cut she had on her face.
So here it is 2 days later and no improvement. Can't afford another doctor visit and so I am asking for advice. Oregano oil and silver worked for me in the past but didn't seem to do it. So now even the shots didn't take care of it. Tweet
