hi girls, i’ve had non cosmetic surgery before and used arnica and even with my boobs i used it before and after my op and i’ve had next to no pain, and no bruising either apart from a little on my hand where the needle went in. i think some surgeons just don’t understand homepathetic medicine as it’s not mainstream, my friends a homeopath so i know a lot about it, we lived together for three years, and arnica is a natural remedy, it doesnt thin the blood i don’t know where they got that from! i got the arnica 30 c from boots, it doesnt matter what brand it is they are all the same. hope that helps xx
