I’ve been having pain especially in my right leg, thigh, angle and some calve areas. Last winter 2020, it was worst. Kept me up at night especially since I sleep a lot with my legs bent. I use an elliptical machine every day and now do over 50 minutes daily, so don’t know if it’s just stress or what from that. But I placed two on each side of right ankle, two each side of calve, two each side of thigh and two each side of knee. I just say, my right leg did not hurt at all. I placed a few on left leg. I do have my good days working out, less pain and good work outs. Today, Sunday, I’ll see if pain is still subsided Monday and Tuesday. Before I place the magnets on my skin, I washed skin with a wash cloth and soapy water and dried off. They stayed on during my work out and when I took a shower, I was careful not to rub onto to the pieces. I blotted towel dry those areas also. One came off I notice and just put it back and, no problem. This was after I put my clothes back on. So good so far. **update 12/15/2021** The magnets stay on pretty good; they’re not going to stay forever so a few fell off after few days. Working out, no pain still. I’m getting a little pain at night in bed; bending of the legs, but daytime, working out on elliptical machine, none so far. I’m happy. 😊
