Initially the relief was fantastic using the larger strap placing the sciaticalm on my right buttock. During the day l can live with the pain or more of an ache and find l do not need to use the sciatacalm as l tend to do a lot of walking but at night l tend to dread going to bed, within an hour of going to sleep I am awake moving the sciaticalm up and down my right leg using the small strap placing it behind my knee on my calf and my ankle I often wish I had ordered three of them ( I do not sleep while using the sciaticalm ) if only I could!. Normally I’II be awake every night between one to two hours.
