Although generally quite safe, counter-irritants may cause rashes and blisters in some people. Sensitive areas, such as behind the knees, may be particularly vulnerable. Test any new product on a small area of your skin before rubbing in large amounts. Products relying primarily on counter-irritants to ease pain include such brands as ArthriCare, Eucalyptamint, Icy Hot and Therapeutic Mineral Ice . Like the salicylates found in many oral pain relievers, these compounds may work by inhibiting prostaglandins, hormonelike substances that contribute to pain and inflammation.
Manufacturers say salicylates seep through the skin to relieve pain.
Topical analgesics containing salicylates include Aspercreme, BenGay, Flexall, Mobisyl and Sportscreme . Be sure to check with your doctor about changes in your treatment plan.
