Causes of blisters under the nose include burns, herpes simplex, contact dermatitis, etc. Symptoms can be improved by topical application of medications, oral antiviral or anti-allergic medications.
1. Scalding: blisters under the nose may appear after scalding, and need to be disinfected in time. Small blisters can be absorbed on their own, while large blisters need to extract the blister fluid and apply scalding ointment to promote recovery.
2. Herpes simplex: when the skin under the nose is infected by the herpes simplex virus, blisters under the nose may appear, and the disease can be treated by applying acyclovir ointment locally or taking acyclovir orally.
3. Contact dermatitis: when the skin under the nose comes into contact with allergenic substances, such as cosmetics, toilet paper, etc., blisters may appear under the nose, and when the blisters are unbroken, glucocorticoid ointment can be applied locally or oral anti-allergic drugs, such as cetirizine and loratadine, etc., can be taken to improve the symptoms.
Due to the individual differences and the complexity of the etiology, the elimination of subnasal blisters should also be based on the etiology of the symptomatic treatment. It is recommended that patients with subnasal blisters go to a regular hospital for timely consultation and standardized treatment as prescribed by the doctor.
