Arsenicum album: If a person feels chilly, anxious, restless, and exhausted during fever—and the burning pain of the eruptions is relieved by heat—this remedy may be indicated. Discomfort is often worse around midnight.
Apis mellifica: Swollen, tender eruptions with burning, stinging pain and itching suggest a need for this remedy. Symptoms are aggravated by warmth, and relieved by cold applications or exposure to cool air. The person may be irritable and very sensitive to touch.
Rhus toxicodendron: This remedy may be indicated for a rash that begins with many small blisters, is red and intensely itchy, and is relieved by hot baths or hot wet compresses. Restlessness makes the person want to pace the room or constantly move around.
