They certainly work, but a little disappointed, as now where the patches have been, my back is now very sore, obviously my neck has reacted very badly, so I would be very careful in future, it’s now 3 days since I’ve used them, and the top of my back has a very bad rash! So I don’t think I would dare use them again,I would rather of suffered the cold rather than the agony I’m now, I have tried. Different pttoduct,To ease my back but nothing worked so far,
