hi this is dr. subhadeep thanks for the opportunity to help you.
as per your description the matter the injury is not very serious, however the site is face and so chances of infection is a major issue.it will be of immense help if you can send me pictures of those abrasions.
first inj.
tetanus toxoid 1 ampule should be taken within 24 hrs. if those r only superficial abrasions then you have to clean those wound with gauze piece and beta dine.after cleaning you can either apply mupirocin ointment or neosporin powder.neosporin powder helps in drying the wound fast.
once the wound is healed there may be scars for that you can get a
dermatologist opinion for creams to remove marks like mender a cream or no marks.first one is more effective.
very rarely if it develops a bad scar,
plastic surgery excision for scar excision followed by
skin grafting can be done.
you can use antibiotics like broad spectrum antibiotics amoxicillin+
clavulanic acid combination 3 times for 5 days
tablet rantack 150mg 1-0-1x5 days
pain killers 1-0-1 and t. chymoral forte 1-1-1x5 days
hope this consultation was beneficial
regards.
