All of these stories are pretty scary to me. I had terrible pain before I was diagnosed with cross and had a Medtronic scs put in last year. I have had 85 to 90% relief using it. I have to nurses from Medtronic who have adjusted it when needed. Sometimes I have some pain below the battery but it goes away. I still take Tramadol in the morning and sometimes sit with my legs up on pillows using a heating pad and that’s very helpful for my left knee pain. Some days I also take a cbd gummy around 4:00 and that makes me very loopy but takes the pain away. I’m 86 but still go to the gym 2-3 times a week and go out socially with friends. I just try not to sit for too long as that gets painful. So sorry to hear about the trouble and pain others are experiencing. Guess I have very good doctors who listen and having the nurses available is a godsend!
