http://www.salonpas.us/ I put one of these on this morning and I am a little bit in love. It's like capsaicin creams, etc... they cause the chemicals that cause pain to trickle out (I feel a tingle) and then your body can't communicate "pain" to you from whatever's causing the actual pain. I had a good thing going w/MSM/glucosamine/chondriton plus prescription mobic/meloxicam. My doctor said I'm too young to take Mobic every day and to quit it. I shot daggers out of my eyes at her. So I am on MSM/glucosamine/chondriton and the salonpas patch. It was like $4 for 40 small patches and you leave them on 1 hr but not longer than 8 hrs... It's been like an hour for me and it's still tingling and feeling better.
