If you suffer from back, neck or muscle aches you may just want to give this product a try. It is not a cure but certainly helps with pain. Recently I was suffering from a very painful, stiff neck and it was recommended that I purchase a tube of A535 cream to help with the pain. Where it did "touch" the pain, it definitely was not long lasting and did not dull it. I found the ice spray in Walmart and decided to give it a try. I am so thankful I bought it. The "freezing" sensation is long lasting and definitely helped me to get off to sleep at night! My son is now using it to ease his aching back muscles after a long day of lifting and carrying heavy products at his job.
