10 Cold Sores Symptoms
Small Lesions
Small lesions or blisters developing around the mouth area are the first cold sore symptoms most individuals notice. These blister clusters can form on the outside or inside of the lip, on the tongue and/or the inside of the mouth.
One or more of the sores might contain clear fluid that can burst and crust over, and the skin around the blisters can appear red and swollen. For external lesions, a topical solution might reduce discomfort.
