Hi, I have ME or chronic fatigue so have an awful lot of aches and pains, particularly neck pain. I use the magnesium spray and it's the only thing Ive found that helps! I use it twice a day when my neck is bad, spray it directly on the area. Your skin might tingle or feel a bit itchy but if it does, that just means you are magnesium deficient, keep using and the sensation will get less and less as you build it up in your system x
