Chemical Burns
Symptoms of Chemical Burns
Chemical burns of the skin usually cause symptoms similar to superficial (first-degree) burns. The area is red, swollen, and painful but does not develop blisters. Sometimes, burns are deeper, with blisters and severe pain. Rarely, a strong acid or alkali will cause a full-thickness (third-degree) burn, that damages the skin all the way through. Symptoms can be severe. The substance can burn the tongue, mouth, esophagus, and/or stomach and cause severe pain and trouble swallowing. Severe complications may follow.
