I had acupuncture while in Canada a few times to treat muscular strains in the chest/forearm/armpit area.
It hurt! But it did feel better after each session...I guess looking back on it, it wasn't the 'miracle cure' some said it would be, but there was definitely an improvement.
It probably didn't help that it was -15/20 C so whenever outside I'd be shivering and I was pretty tense about having needles stuck in my chest and near my lungs especially after they told me there was a small chance of one getting all the way to a lung and deflating it. Then again, I am a hypocondriac.
EDIT: spelling.
