Herpes zoster forming hard bumps can be treated by topical medication, irradiation laser and surgical excision. 1. After herpes zoster heals, the blisters dry up and the scabs fall off, which may leave temporary erythema, or there may be keloid scars, which are usually related to an individual’s physique, and there is usually no obvious pain or itching sensation. In the early stage of scar formation, you can use drugs such as compound heparin sodium, allantoin gel, human collagen-like silica gel, etc., which is helpful in promoting skin repair. 2. If the hard lumps seriously affect the appearance, you can choose to use carbon dioxide fractional laser to promote the regeneration and remodeling of collagen tissue in the scar area. Surgical excision can also be used for larger keloids or old scars. Patients with shingles are advised to visit hospitals for targeted treatment or therapy under the guidance of specialized doctors.
