Cold sores and ulcers are extremely common amongst both children and adults. Cold sores are caused by the herpes simplex virus type 1 and can be passed from person to person and found on the exterior of the mouth or around the lips. Treatment for these conditions is usually a cream or a gel that targets the area and soothes any pain and discomfort caused.
Treatment ranges from blister patches and creams that are designed to be placed over a cold sore to soothe and protect it or a soothing gel to be applied to the ulcer.
