I ordered this product on the recommendation of friends after I suffered a groin injury. Anti inflammatory meds weren’t doing much and I was in debilitating pain for a few weeks. I was desperate for relief and found your product stopped the jabbing pain almost immediately. I admit I used it for more than the recommended 7 days because it’s the only thing that helped, but now I only use it intermittently on the days I try to push my recovery too fast. I’m 71 years old and wouldn’t wish a groin injury on anyone but this stuff really works and am grateful for the help.
