Hands are scalded by ice 2 hours later still pain, one is related to the skin nerve damage, the second is to show that the skin injury is more serious; patients can be improved by cold water rinsing or medication; if the pain is still not relieved, it is recommended to go to the hospital in time for examination. 1. Skin nerve injury: when the patient’s hand is scalded may damage the nerve tissue under the skin, so although ice can temporarily make the blood vessels contract to relieve the pain, but when away from the ice, the pain caused by nerve injury will become obvious. Patients can continue to apply cold compresses or cold water rinses to achieve cooling, pain relief and anti-inflammatory effects. 2. Scald injury is serious: when the patient’s hand for 2 degrees and above burns, damage to the dermis, ice for 2 hours can still produce pain. Patients can take oral ibuprofen, diclofenac sodium, etc., or use lidocaine gel for pain relief. When the patient’s hand burns after ice packs are still not relieved, it is recommended to promptly go to a regular hospital for examination and treatment under the guidance of a professional doctor. All drugs should be used under the guidance of doctors.
