Frequently Asked Questions


  1. How does Heel NO Pain by Biochemistry ™ work?

    Among its active ingredients is Lidocaine HCl which directly soothes the nerves of your feet that transmit pain. This is a similar ingredient to Novacaine, which medical doctors and dentists inject in their patients to completely deaden pain.
