on it now? Worried? Dr. gave me Silver Sulfadiazine. Used 4-5 x day for first week. No fever. No red streaks. Has been getting smaller but won't seem to scab. I'm unclear about what I should expect and what it should look like. Is a 3rd degree burn, 1/2 the size of the palm of my hand. My daughter said the partial scab looked greenish?!
