I want to thank the person who left the testimonial about the sternocleidomastoid muscle issues. I too suffered from the same inflamed sternocleidomastoid (scm) muscles...Who knew that these neck muscles could reek some much havoc? Since I've been massaging my own neck every day (with thumb and index finger) that started to help. I also got some real time pain relief and started using that, and I think it has speed up the healing of these muscles. I actually like the smell, my wife was neutral about the smell. 2 months ago I thought I was falling apart. Now I've got about 90% of the pain and tenderness of these muscles worked out...It is kinda like having plantar fasciitus in your neck. I'm so glad I found this product. It has helped recovery.
