Th dr said i have tonsillitis on tuseday i just got to get my antibotics on friday how long will it take for me to tlk good?

A few days, maybe...: Tonsillitis etc can be due to viruses & bacteria, but most commonly the former. In these situations, we'll get better w/time but nothing we take, including antibiotics, will make infection go away any faster. If we truly have strep throat, then antibiotics such as penicillin can make a difference. Check out http://www.Mdcalc.Com/modified-centor-score-for-strep-pharyngitis/ to determine difference.
