My husband had the Nevro Senza trial, then had the device implanted in June of 2021. He is very well pleased with the relief he has gotten in his feet and legs. Especially the feet. Since getting his, 2 of our friends have gotten one implanted. One of them is so, so happy with hers. The other friend just got his yesterday and is experiencing some pain today with the implant itself, but his feet and are NOT hurting. Op site pain will go away. Hope you get relief!
