I usually get cold sores either on my chin or cheek when I'm tired and rundown and i slept terribly last night. Result = i get a really itchy cold sore on my chin today, now bubbling away like bubble wrap.
i keep finding conflicting answers regarding zovirax cream on dr google. i do have some aciclovir tablets but no leaflet as i just keep the tablet strips in my hand bag / desk at work for emergencies.
is it safe to use the cream / tablets or are there any more natural remedies you can recommend?
thanks in advance
