Hello and welcome to Healthcare Magic. Thanks for your query.
It is very unlikely that the mild injury which you had sustained a week ago is responsible for the fever
and headache now. Fever is the sign of an infection and it could be possible that the tonsillitis
is causing the fever and headache. Moreover, the nature of injury does not seem to be a significant one and you have not had any immediate effects or comp[lications due to the same.
So, you need not worry about the head injury
. I would suggest that you take paracetamol
for the fever and frequent saline or betadine
gargles for the throat problem. In case your tonsil problem flares up or you are having persistent high grade fever, then you may need antibiotics also.
Wish you all the best.
