If you're not having trouble breathing due to your cold, you'll most likely be fine as long as you're not doing intensive work. Regardless, I would still recommend being cautious; if it hurts, take it off as soon as you can. I'm not sure if this can apply to you, but when I bound daily, if I was having bad chest pain, I would loosen the binder because it was fastened with velcro; I'm not sure if something like that can be done with pullover/zipper binders, however.
