Is that for joint or for muscle ache? I usually just go to sleep if my neck gets strained and the muscles relax. Hanging upside down helps, too, but the power rack is in the garage so I don’t do that much any more. It took me six months to learn a very involved chi kung (qi gong) form in the nineties, but since then I don’t have much neck discomfort. Chi kung was definitely the most effective approach. When my husband took a long exam that, in this day and age (2001), had to be hand-written, he used capsaicin cream for writer’s cramp and that helped considerably.
The Celadrin Cream is for joint pain. For muscle aches, I usually take a dose of ibuprofin and either use moist heat or an ice pack., then relax for 30 minutes while they work.
