The warmth lasts long but cant feel enough of the warmth
The healing patches were okay. They do last long about 6-7 hours. I wore them to work on my bad cramp days. Sometimes, I could not tell if they worked when sitting down. When standing up, I could feel the warmth.<br />I could not feel the warmth through my undergarments after following instructions, so I had to adhere the patch to the inside front of my pants. I wore tight yoga pants because it hugs my abdomen compared to jeans. That made me feel the heat better.
