Lower left side back pain upon waking...help

Not every night but every so often I wake up with terrible pain in the lower left side of my back. Could this be kidney stones? Is there a way to break them down before attempting to pass them as I cannot fathom passing these bowling balls...

I just started juicing. Is there a specific remedy that would aid in their breakdown?

FWIW there aren't any ND for 300miles from me :(

Thanks. Tweet
