If you have a vascular blockage in your legs, it is important to consult with your doctor before using the Revitive leg device sold in pharmacies. While the device may help with circulation for some individuals with leg circulation issues, it is not recommended for use in certain situations, such as during pregnancy or if you have symptoms or a diagnosis of deep vein thrombosis. It is best to seek medical advice before using the device to ensure it is safe for your specific condition.
