Thank for asking to HCM
I really appreciate your concern, looking to the history given here the chances of infection is very likely, if I would be your doctor then I would treat this with the following medicine,
1) Tab Ibuprofen
400 mg three times in day
2) Tab Ciprofloxacine 500 mg twice in day
keep the are clean keep the hot fermentation continue and no need to worry about this every thing would be alright soon, hope this information helps you have nice day.
