I didn’t know you could take arnica orally. I’m too cheap to pay for pain relieving lotion/gel but as I age that may change! Husband is in construction and I’m in food service-tired and sore bodies!
He left a professional career to start his own construction business and I went from a professional job to stay at home mom then back to waitressing. We aren’t worn out from decades of constant physical labor but it still affects us a bit.
another thing to try is capsacin cream (sp?)- you probably have tried it- but capsacin works to dull pain- works pretty well
I’ll check out htat hydrogen trick=- did it shorten the length of your cold? And you cold turned into bronchitis after using it? Did i misunderstand your post?
