The burning sensation in most cases is a good sign, which means that the drug in the ointment has an effect on the patient’s diseased area, and the local blood circulation will heat up due to the effect of the drug, which is a normal phenomenon. However, the burning sensation in some patients with ointment may also be related to allergy to ointment or local skin injury, which can be observed by local skin changes. Because most of the ointments contain ingredients to promote blood circulation, relieve blood stasis, reduce swelling and relieve pain, some of the ingredients will stimulate human skin, and it is normal for patients to have a slight local burning sensation. Usually, this burning sensation is mild, and the symptoms will be reduced after the ingredients in the ointment are absorbed by the body, and the symptoms can gradually disappear after the ointment is removed. However, a few patients may have obvious redness, itching, stinging, and in serious cases, rash, papules, blisters and other adverse reactions after using the cream, indicating that the patient is allergic to the drug ingredients in the cream. At this time, you should immediately stop using the medication and wash the area with water, soap and water or saline to clean the drug residue on the skin surface as much as possible to reduce the adverse reaction. It is also recommended to seek medical examination and consult the doctor whether it is necessary to change the treatment medication, and at the same time, anti-allergic drugs can be selected to treat local allergic reactions under the guidance of the doctor.
