Thanks for the query
If u have had protected sex then it is least likely that u will suffer from an STD
but the abrasion on the shaft is an issue.
99.4 is not fever
, it is considered as fever from 99.6, since u have a focus of infectin (the throat) lets not search elsewhere.
Take levoflox 500 once a day for 5 days, gargle with betadine
gargles twice daily. U should be alright
Have a healthy life
