Sumifun 4% Lidocaine Pain Relief Patches 15 Counts Maximum Strength Numbing Gel Patch for Back Knee Neck Joint Ache Muscle Soreness Topical Analgesic FSA or HSA Eligible

Great for stiff or painful shoulder. Probable work great for the knees.

Bought Amazon brand. They did not stay on skin more than two hours. They were awful. Sumifun patches worked as well as prescription. Stayed on 12 hours. And dulled the pain. Great product

Pain wise I think the patches worked pretty well but the patches themselves were hard to deal with because the edges kept rolling. It was impossible to keep the patch on a specific area for very long. I don't know what the answer is...maybe make the edges thicker than the reast of the patch? I may just have to go back to the roll-on Lidocaine, however, if they can improve the patch, I would defnitely try them again.

These are great. They work well, stay put and are easy to remove

I use this on my shoulder and it helps but the adhesive doesn’t work for the 8 hour it’s supposed to. I rarely get 1-2 before it starts coming off.

these were great and they stay on and don’t move around.

This patch is great. This is the first time I have used them, and I am very satisfied. I will order them again. Easy to apply works fast and lasts long.

This product is excellent and worked very well! I will order this again! My order came overnight and that was excellent because I really needed it!
