This is just my personal experience, I am not a health professional. I have right breast pain that runs up my neck, radiates in my shoulder and down my arm into my hand.
I chop four garlic cloves and let sit for about 10 minutes to activate the Allicin, I then mix in raw honey about a tablespoon.
I chew a couple of times before I swallow and this provides pain relief almost instantly. It only lasts a few hours though.
