I experienced immediate pain relief in a day! I was in disbelief because nothing has ever worked so quickly. My daughter was having the same knee pain and I gave her one to try and she has gotten the same results! She is climbing 3 flights of stairs faster and without the pain she was having before wearing the knee compression sleeve. We are so grateful! Thank you making an awesome product. I’ll be order another for me, husband and daughter and I’ll be trying the socks!
