JointFlex Far Infrared Back Patches, 5 Day Wear, Drug-Free, 3 Patches | Supports active mobility, For lower back muscles, wear up to 5 days, water resistant, non-heating, synthetic, 7.87" x 3.93"

They work if u have pain pretty much anywhere. Helps so much better than Salonpas. I found these after trying several other products. These work the best and stay on a few days. They take the edge off and give some relief. They helped in bad situations.I recommend.

I felt improvement within 24 hours. The tape items started coming off at 48 hours.

I am overweight and sit much of the time. This causes me to have significant back pain. On the advice of my SIL in Iceland, I ordered these patches and tried them. I wasn't really expecting them to work considering that there is no medication involved. The first few hours I didn't notice much difference, but gradually I became aware that my pain had lessened. The next day it was gone altogether. The patch stayed on very well the first four days (even during showering), but on the fifth day it began to roll a bit. The pain relieving effects continued throughout the entire five days and even lasted through another day without it. I wish they were a little less expensive, but I will continue to purchase them because they work so well!

The first one was great. I put on another one and had an adhesive reaction. If you are prome, avoid.

Muy poca mejoría. Hice reacción al pegante

I've tried many different brands of therapy patches without good results. These joint flex infrared patches give me relief from my sciatic pain.

These are a life changer! Helps my back so much!!!

Does ok. Doesn’t fully ease my back pain. They do stick pretty good and lasts a couple of days
