Hi,
I'm sorry you had to deal with something like this. I was bitten in the face by a dog with I was seven. My scars are okay, but I'm writing to encourage you to get a second opinion about your son's scars. ER doctors are great, but I would recommend 1 trip to a doctor that specializes in skin and scarring just to see if there is anything else that could be done.
My recommendation is due to family experience. My nephew had "birthmarks" he was born with that the doctor said would go away on its own. They never did. They got worse; they got bigger. He had 2 huge ones on his back, but the one on his forehead was the real pain. Not only are they prominent in all his baby pictures, but he could hardly play when he went to church or playdates because all the kids wanted to come up and "play" or press his mark. When my brother took my nephew to a new doctor the new doctor asked why something wasn't done when my nephew was born! Finally at age 4, my nephew had surgery done to remove him. He has some scars now, but they are well hidden with hair on his forehead or with his shirt. Had something been done when he was born, he wouldn't even have scars.
Of course birthmarks are different from scars, but you would have more options and peace of mind by having gotten a second opinion.
Another reason for my advice: my daughter has a birthmark. I drove an hour to get a second opinion. The skin specialist (Dr. Gahli, pediatric dermatologist in Grapevine) said it was exactly what my regular pediatrician diagnosed! I didn't feel like my time was wasted. I was relieved and now have even more confidence in my pediatrician.
The good news is anything that happens to little ones usually heals really well, but science has really come a long way. You never know if there is some great new product or procedure that would help make the healing even better.
Best Wishes,
Holly M.
