pain
"I used the gel once, as prescribed and broke out in to a rash  all over my body. The rash is called Erythema multiforme. I  was covered in bright red,raised welts and hives for close to two weeks. The experience was itchy, uncomfortable and over all unpleasant.  
My Dr. said to stop using the gel but the most frustrating part was there was nothing anyone can do. It simply needed to "run it's course!"
Use at your own risk!"
