What needle for im injection of medication in small adult?18g 19g 21g 23g or 25g? 25g seem ok bt nurse said too small for im. any larger seem painful!

21 or 23g.: I agree that 25g may be unnecessarily small. 21g or 23g would be better. Pain comes less from the size of the needle and more from the technique of the injection.
