Shingles attacked my inside right knee with pain radiating to the thigh and accompanied with extreme sensitivity to touch. It was so sensitive I couldn’t sleep with a sheet over my right thigh and knee. I used my P180 to treat right side: lower back, hip, thigh and knee two months after the beginning of shingles pain. I was able to resolve 85-90% of pain and sensitivity within 39 days treating 3x’s a week. Thankfully I could tolerate wearing slacks again and could begin to kneel on that right knee. At 76 I am grateful that my personal unit has returned me to yoga, water aerobics and walking! Thank you Bioflex🙏
