Query: yamuna foot wakers

I wear a high heel a lot,also i do horseback ridding so i wear a tight boot for hours.My physiotherapist recommended using yamuna foot wakers ,its small light and i can take it with me in the bag.easy to wash.the video that comes with it helped me a lot . Everyday night while watching the T.V i use it.i feel discomfort when i put all my weight on my leg while standing on it but i still keep standing since it will help my leg.
