ah i went back and found the article about frozen needles and it says that frozen neddles cut pain, in the article it says the coldness of the needle acted as a local anesthetic. in the study 77% of the patients siad that the injection was less pain full and 18% of the people said it hurt more, and 5 percent didnt feel a difference, plus these patient's werent geting steroid injections, the injections were anti-wrincle injections on both sides of the face. ouch
so u be the judge and try it for yourself.
