Multiflex Extra Strength Cream works well at getting rid of muscle and joint pain almost immediately. My mother was having joint and muscle pain for quite some time in her shoulder and upper arm. She rubbed a bit of this into both areas and within minutes the pain was gone. She did say that while she rubbed it in she felt a warning sensation but soon after it left her chilled and feeling cold. But the pain went away for roughly an hour. It says on the directions to use 3-4 times daily for up to 7-10 days. This product does exactly as advertised. The only complaint one could have is the menthol and camphor scent is quite strong so I'm unsure you would want to wear it going out. But on the bright side if you had a cold it would work wonders breathing it in as it would most likely act as a decongestant.
