I have that issue with certain types of chain links. I returned J285373 because the chain was irritating my neck. The thinness of the links and the style of chain also makes them very sharp. I also had some issues with the chain on J289588 and decided to have my jeweler change the chain. Both were generic open link chains. The thinness of the links was like having sharp fingernails grating against my throat and collarbone.
