Is it normal for swelling to increase after spraying Yunnan Baiyao aerosol?

Generally, mild swelling for a short period after spraying Yunnan Baiyao aerosol may be normal. However, if the swelling persists and worsens or is accompanied by other discomforts, it is considered abnormal. In such cases, prompt medical attention is recommended. Detailed analysis is as follows:

If there is local bleeding or tissue fluid exudation in the early stage of injury, mild swelling may occur shortly after spraying due to the drug's effect or local reaction. Typically, the degree of swelling does not continuously increase and will gradually subside, possibly accompanied by slight stinging pain. This is a common manifestation during the body’s healing process, and continued observation is acceptable.

If swelling persists for more than 1–2 days after spraying and continues to worsen, or is accompanied by symptoms such as redness, warmth, itching, or rash development, it could indicate an allergic reaction to the medication's ingredients, or suggest infection at the injury site, or irritation from foreign substances due to failure to clean the wound before application. In such cases, discontinue use immediately to prevent further worsening of swelling.

Prior to using Yunnan Baiyao aerosol, the injured area should be cleaned, and the product should be used according to the instructions. If abnormal swelling occurs, do not attempt self-treatment; seek timely medical evaluation to determine the cause and receive appropriate treatment.
