After a herniated disc I have since continued bad tension in the entire back. This small pillows made for very effective relief. During the 15 minute interval I put it to me in a sitting position slowly to the spine upwards, so that from buttocks to the neck all abkriegt its part, while I put the pillow in particular at locations where it spans especially hurts and "knubbelt". Since I use it, I can move better and may even renounce drugs that otherwise in times of particular stress on the complaints helped me drüberweg.
However, I leave it after some time of my old mother, who was able to walk because of spinal degeneration barely. Her pillow has this helped. Although your symptoms are still present, but considerably softened. As a substitute I have (surprisingly affordable) Ecomed 23310 Shiatsu bought Massage Cushion MC-80E massage pillow, which I want to do not imply product endorsement - but this new cushion is just as effective as the HoMedics, but has three advantages: 1) it is even quieter, barely audible, 2) the heat switching is plain to see when HoMedics the heating effect is rather inconspicuous and 3) I like it better that the control panel is einglassen the pillow and thus another cable for the remote control is omitted.
Total both pillows fully meet their purpose and are very effective in healing and back problems that have to do with tension.
