The duration of the numbing effect provided by foot numbing spray can vary depending on factors such as the specific product used, the concentration of the active ingredients, and individual differences in skin sensitivity. Generally, the numbing effect can last anywhere from 30 minutes to a few hours.
It's important to note that foot numbing sprays are designed to provide temporary relief and are not intended for long-term use. The duration of the numbing effect should not be relied upon as a measure of the underlying condition's severity or progression.
If the pain persists or worsens despite using foot numbing sprays, it is advisable to consult a healthcare professional for further evaluation and appropriate treatment. They can help identify the underlying cause of the pain and recommend more suitable and effective interventions to address the issue.
