and control your patch locations. This will help you find the right spot.

The theoretical max of using the patches is 3 full ones every 12 hrs.

But for you I'd start with one patch cut in half, and put behind each knee,
for at least a week. This will tell you if it is the knee area that is causing your
problem.

If that does not work, move up, to the sacral area...1/2 patch on each side.
Do that for a week, and see what happens.

If you apply the patches all over, you will not get a definitive answer as to
the placement.

I personally have not had good response from putting them on the feet.
Whenever I have a huge pain...I try to block it higher up, from where it is really felt.

Also for burning and tingling (which is not frank pain)... you really should try
Thiamine (Vit B1), in high doses. This can really help paresthesias..which what burning/tingling really are. Pain..as in sharp/penetrating pain, is much
different. Start at 200mg a day, and up to 300mg a day in divided doses.
This is an old remedy and still works for some people.

And for burning, you should check to see if certain foods, make it worse.
Histamine is present in tomato sauces, and can trigger this for some. Same goes for Monosodium glutamate..a common food additive and also very
common in restaurant foods.

Burning/numbness and tingling also accompany low thyroid functions. So I assume you have had that checked out?
