Can sodium diclofenac aerosol treat blood stasis?
Under normal circumstances, sodium diclofenac aerosol cannot directly treat blood stasis; it only helps relieve pain and inflammation associated with blood stasis. It is unnecessary for simple cases of blood stasis. If in doubt, it is recommended to consult a doctor in advance. Detailed analysis is as follows:

The primary function of sodium diclofenac aerosol is anti-inflammatory and analgesic, working by inhibiting inflammatory factors. It is suitable for pain and swelling caused by sports injuries, strain, or similar conditions. Regarding blood stasis, the aerosol cannot promote the dissipation of stagnant blood or improve blood circulation; it only alleviates possible inflammatory reactions accompanying the affected area.
If blood stasis results from trauma and there is no significant pain or inflammation, using this aerosol offers no actual therapeutic benefit and may instead cause skin irritation due to improper use. However, if blood stasis is accompanied by severe pain, swelling, or inflammatory response, the product may be used under medical guidance, combined with methods such as cold or hot compresses to facilitate absorption of the blood stasis.
Before use, the underlying cause of blood stasis should be clearly identified to avoid blind medication. The spray should be strictly applied according to instructions only on intact skin, avoiding damaged areas. Discontinue use immediately if discomfort such as itching or redness occurs after application.
