Several years ago I was involved in an automobile accident in which I was rear ended at high speed. The results of the impact bulged/ slipped discs and shifted the vertebrae in my lower back. My occupation is already a physically demanding one, so the level of discomfort I experience on a daily basis is sometimes excruciating. I take pain medication daily, and after years of use my body like anyone else’s with extended use has built a tolerance to them. They only keep the edge off anymore. To assist the meds I have tried literally every pain relief otc gel, rub,or cream. The majority of them have the same active ingredient. Menthol or camphor. Different slick labeling, same product. Or maybe capsaicin. Dear God don’t accidentally touch your face or eyes after application. At least that pain will temporarily make you forget about what you rubbed it on. Then I found Rubber Arm. First thing my eyes go to on the label is the active ingredient. Alas, something different! I tried it and WOW I’m glad I did. This has helped me better than a prescription compounding cream I pay $45 for even with insurance. I highly recommend trying this product. Keep expectations reasonable…nothing is a miracle cure for persistent injury pain of my nature. I have learned to accept that…but this I assure you. Rubber Arm will stay on my nightstand from here on out. If you suffer from just general soreness or aches and sprains, this stuff is a no brainer. You WILL feel better. God bless.
