Does it hurt when spraying watermelon frost powder on oral ulcers?

When sprayed onto oral ulcers, most patients will experience a certain degree of stinging pain from Bingpeng Powder (Xigua Shuang). This pain response primarily results from the medication's direct action on the ulcer surface and is a normal manifestation of its therapeutic effects—clearing heat, detoxifying, reducing swelling, and relieving pain. Although Bingpeng Powder is generally considered to have mild irritation, some individuals may experience more noticeable burning sensations due to individual differences or varying severity of ulcers. This discomfort is usually temporary and gradually diminishes as the medication takes effect. To minimize pain, patients are advised to apply the spray gently and avoid forceful spraying directly onto the ulcer. Additionally, maintaining good oral hygiene, drinking plenty of water, consuming fresh fruits and vegetables, and avoiding spicy or irritating foods can promote healing. If the pain persists or worsens, medical attention should be sought promptly to rule out possible causes such as drug allergy or bacterial infection.
