Please remember me in your prayers. I`m having knee surgery on Friday. I have torm cartilage that needs to be repaired and wear that needs to be cleaned up. I`ve been having so much pain that its hard for me to sit with my knees bent. It really bothers me in a car ride. I sure hope this helps. Its slowed me down a lot this summer. I`m doing my right knee first. Then in a couple monthes I need to do the left one. Also my brother is having gallbladder surgery this week and my 20 yr. old nephew is having his wisdom teeth cut out. A lot of surgery this week for my family. Thank you guys so much!
