Anyone that has recently suffered a leg injury of any kind, or has poor blood circulation, should first ask their doctor if leg compression therapy is safe for them. Not following your doctor’s instructions could impede your recovery timeline, or cause serious injury to your legs and/or feet. In addition, using the massager for too long on sensitive areas can cause major discomfort and/or injury. We suggest that you try using the leg compression massager on a low or medium intensity setting, for 20-30 minutes per session, especially if you’re healing from an injury. To ensure your safety, do not use the massager without the approval of your doctor if you are: pregnant, diabetic, have a pacemaker, recovering from surgery, or are suffering from migraines, neuropathy disorders, disc protrusion or spinal inflammation. In addition, make sure to keep the RecoverMax out of the reach of infants, toddlers, and children. This product is not a toy and should not be used at such.
