Sharp, sudden, radiating, but changeable, pain symptoms are Berberis’ specialty, whether caused by inflammation of joints or backs, colic or menstrual periods. Its low back and sciatic pain radiates downward to the thigh and are greatly aggravated by standing. Berberis also applies to tight, pressing headaches and sharp, changing urinary pains - but be sure to check with a professional if kidney or bladder may be involved. Whatever the ailment, sudden jarring motions can cause Berberis pains to radiate even more.
