Tiger Balm Pain Relieving patches! I don't go much for "alternative" treatments, but my daughter sent me a bunch of these and I like them. Tiger Balm contains no actual pain medicine, therefore there is no conflict with prescribed drugs. Tiger Balm's active ingredients (menthol, camphor, capsicum) act, supposedly, as a counter-irritant that temporarily utilizes the same neurotransmitter pathways as pain, such that pain signals don't get through. Sort of. When wearing a Tiger Balm patch many people experience heat, but I get a cooling sensation. This morning I awoke with a crampy lower hamstring- I applied a Tiger Balm patch to the area and it feels good now.
Note that the patches smell a bit weird, and they are adhesive free- they cling rather than stick. I get no skin irritation at all. I have googled the heck out of this product and find no contraindications for use following knee replacement. Everyone have a great day!
