Cora Heat Relief Patch - 2 Pack - Soothe Cramps for up to 8 Hours with Heat from Activated Carbon - Adheres to Your Clothes to Ease Cramps Exactly Where You Need it

I don’t know the magic behind these heat pads, but I will be a supporter of them for the rest of my days. They’re lightweight, provide such a strong warm feeling that you may forget that you’re in pain! I do stand by these. I frequently wear them to pilates over my leggings or shorts when I’m dealing with period cramps. I’ll also wear them while lounging around at home in my pajamas. Very worthwhile and a way to avoid taking painkillers

These heat up quickly and are easy to apply. They are thin and difficult to see under clothing. Definitely helps with cramp pain relief. They stay warm for a long time. In fact, they were still warm when my daughter was ready to remove them. They weren't horribly expensive, and the portable heat makes it worth a try. It's nice not to have to recharge a bulky heating unit made for a similar purpose.

I love these. They help so much on my cycle. I also use them for lower back pain. I always have one in my period bag😉. They really do help with the pain. Just buy it and try it.

These get slightly too hot IMO, but I think I might have a heat sensitivity. For others, it’s very soothing. I used these at work & they typically last about 6-8 hours. The heat peaks around 4 hours, then slowly tapers off. I’ve purchased these time and time again. They do get old & not effective if not used within a few months of purchase, so I wouldn’t keep them as an emergency stock. There’s great during winter or when wearing a few layers of clothes. I have definitely recommended these.

These are magic and worth every penny!
