Is that a spray and then you rub it in ? Does it smell/stink ? This is the stuff we use, I got psoriasis on my 3 of my knuckles about 5 years ago and tried cortisone crème that Dr. recommended and was putting it on a few times a week and it wouldn't go away . I tried this on my knuckles and it went away on 2 of them and the other one is almost gone. I put in on once every week or two. Like I said , I think the bigger the joint the less affective but for muscle pain it works wonders.
This is a big stick and no mess putting it on. As I was typing this , I did an experiment. I put some on the bottom of one foot and in the palm of one hand. I have neuropathy in my hands and feet sting and they tingle and sting . It's been about 5 minutes and I can feel a difference.
If you have neuropathy or sore feet from being on them all day , try it one foot at the time and see if that works. Wife takes a the drops every morning and they make a huge difference for her. I was taking a big dose with not much noticeable difference.
