It is an amazing product for hydrating after you’ve been outside playing or working or whatever and sweating excessively!

THIS PRODUCT ARRIVED WITH GREAT HASTE,WHEN YOU ARE IN PAIN THATS A WONDERFUL THING. THANK YOU SO MUCH

My previous medical provider prescribed me a box of 5% lidocaine patches, which gave me decent relief for my episodes of lower back/SI joint muscle pain. Since I no longer have that provider or the same insurance coverage, I sought these out as an over-the-counter alternative.These are the same size and seem to work almost as well as the stronger prescription ones -- with a few caveats. First, these patches are a little flimsier than the prescription ones, so they're harder to apply. They have a tendency to fold over on themselves while you're putting them on and seem to come loose a little more readily. Second, the prescription ones seemed to be over-saturated with lidocaine gel -- as in it was dripping off the patch and kind of messy. These have less gel and are therefore less messy, but maybe also somewhat reduced effects as a result.Finally, it's important to note that both the Rx strength ones and these take some time to work. It's not immediate relief. It's more like ~2-3 hours after you apply them, there's a noticeable reduction in the intensity of pain. Definitely not 100% pain relief, but still helpful as part of your overall "arsenal" of approaches. I've found that 2 patches placed side-by-side on my lower back work best for SI joint issues.

Great for keeping pain at bay

Item was as described. Sticks better than some other patches I've used. Are simple to apply and supply expected pain relief.

the gel feels nice but the numbing isn't that strong for my discomforts. using on back and any flat area n it's fine but if you were to use it on your arm/elbow any bending of the joint will make it go loose cause the gel doesn't have strong adhesive properties and cutting it up didn't help because less surface area also seem to make it not stay on as well.

Seems to work as well as the name-brand product that dominates this product type. Adheres well. Very good value for the money.

Do not waste your money on this product ... Amazon will not accept returns. I ordered multiple quantities ..... while I can understand that patches from an already opened box can not be returned (as fewer items than originally in box) ... I am not allowed to return full boxes (per Amazon) (also for any such product, purchase only 1 item, see how you like it, then order more boxes if you like it, never purchase multiple boxes before trying a single box). My best patch recommendation is the "Amazon version" of the patch, has less odor (smell) than this product.
