I found some extra-strength pain relief cream that has an instant effect. It works immediately for sore muscles, inflammation, arthritis, and neck and back pain. It contains emu oil and arnica for enhanced relief and healing. I found it to be much more effective than many of the brands I’ve tried in the past. A small amount goes a long way in adding to the value of the cream. It was definitely of great quality, and I had no neck soreness once applying it to the back of my neck and shoulders that were sore the day I received it. It’s perfect for athletes, those who work out on a regular basis, or those who work in labor jobs.
