Usually the lesions start as reddened bumps which evolve over hours or days into blisters/open sores which crust over, dry up and heal. Sometimes a second crop of lesions occur. The initial infection may be severe and have more generalized symptoms such as fever, headache and muscle aches. However, these lesions are not the only symptom of an initial outbreak. Symptom...
