"the gel helps with the pain but my stomach was a little upset, i got a mild headache and i felt very drowsy and out of it. yes i know it&#039;s the gel but i still had side effects. i only rubbed in a small amount. i can&#039;t swear by it but i think it also caused me to have several anxiety attacks which i think are related to the woozy out of it feeling. it says it makes you dizzy on the box."
