I had this experience with a different bath salt package from Saje before (Cellucleanse) which I assumed was due to the black pepper oil in it and I warned my husband that he would have a spicy bath if he used it. He used it later and was like "There was no pain; I have no idea what you're talking about." So then I tried Yoga and no pain. Today I tried Unwind which smells amazing (so citrusy) and I still had to change the bath water because I just couldn't take it anymore. On the plus side, no redness or hives or anything: if I showed my painful legs to someone they'd have no idea anything was wrong. So mostly it just feels like you're sitting in scalding water but only on the backs of your legs. I did follow the amount instructions and swirled it around so that it wasn't all sitting with a different density in my bath but it's just weird. It's just the backs of one's legs no matter how much of one is submerged.
