Your leg massage should never cause you any kind of pain. If it is, stop using the RecoverMax immediately. Carefully remove the straps from your legs, and wait a bit before trying to use them again. Rest your legs and check them for redness, swelling, and discomfort. Make sure the straps are positioned properly on your legs. Use the included thigh and calf extension pads to ensure that the straps are comfortable. We also recommend that you decrease the massage intensity, choose a different air compression mode, or use less heat if you feel pain. If the settings are already at their lowest level, though, and yet you still feel pain, then stop using the massager entirely. Consult your doctor for further instructions before attempting to use the massager again. It’s essential to always heed your doctor’s safety advice to avoid injury, no matter who you are or how much fitness experience you have. Remember not to use the massager if you are pregnant, diabetic, have a pacemaker, recovering from surgery, suffer from migraines, neuropathy disorders, disc protrusion or spinal inflammation.
