After engaging in a 10k run, I was trying to sleep but my quads and knees were throbbing and sore. And then I remembered the lotion! I rubbed Imperial Blend lotion all over my legs and knees (which were visibly swollen). The throbbing stopped almost immediately, but the skin on and around my knees was warm and tingling for several minutes. Then the warmth stopped and the throbbing too! I was finally able to get to sleep.
