The heat here is causing my feet to swell & the pain in my soles is unbearable. I can't wear my slippers or even my fly flot sandals, & going barefoot hurts too. Anyone know what will give relief please? (I can't take herbs or put anything from a plant on my skin because I'm on the Guaifenesin protocol, otherwise I'd use arnica gel or peppermint lotion). Thanks, don't know how you folk in hotter places manage!
