Ice and Heat for Headache
Injuries can occur from burns if heat, such as through hot packs, is too hot or left on for too long. Patients with reduced sensation, such as numbness or diabetic neuropathy, should use heat and cold with care. Ice burns can also occur if the skin is cooled too much. Some conditions can be worsened with heat or cold, however generally, and especially in comparison with other treatments for pain, hot and cold packs are pretty safe.
