I was skeptical that these patches would do anything to my pain. I tried them twice and I was shocked to realize they make a world of difference. I put them at night before going to sleep and I woke up feeling like I did not have any injury! The difference was like night and day. Now, I am hooked and addicted. I decided to enroll in the subscription, so, I always have patches available when I need them. I dance 4-5 times per week, so, I always have some sort of pain everywhere. ActivMend has been a lifesavior! I use them for my lower back, my upper back, my sciatica, my knees, you name it. I even gave a couple of my patches to my dance teachers, and they worked for her! So, do not hesitate to try these. They’re absolutely amazing!
