Hello I'm Currently On Meds For Cellulitis. I'm Following My

Hello I'm currently on meds for Cellulitis. I'm following my plan and eating at the correct times between pills. But I do feel slightly unwell and I'm not sure if it's because I've been eating less or anything else. Personally I think it's down to eating. But I've had an upset stomach for a number of hours and have a weird taste or chlorine in my throat. Is this anything worth getting checked? Thank you
