This is Dr. David
I am another expert here
it sounds like your sore throat got worse on Sunday with a lot of coughing and is better by Monday.
this does not sound like a drug reaction to Bactrium.
it sounds more like a short temporary viral infection causing viral pharyngitis or from acid reflux.
you should talk to your doctor about your sore throat.
but I bet your doctor will tell you to continue to take your bactrium antibiotic.
let me know if you have other questions.
