Oh, no, John!!!! I'm sorry you had such a bad hab experience. I rub them on my neck for neck spasms, they feel better than the headaches caused by the neck tightening. True, I did feel it for about 3 days and had some surface soreness, but it helped. I used a lotta hab, too! The soreness might have come from trying to rub out the neck spasm. Here's where TWISTER{TM} is really needed. A nice stretch, plenty of habs and juice up some pineapple salsa, combine all three with your chosen loved one, and there you have it. I think a course in massage and chiles would help a lot of us. Yes, could be very helpful indeed. May your chiles thrive, Judy Jalust@aol.com
