Unless you got some dirt or rocks in there that short of a period should not have done any damage. Have you tried thoroughly cleaning it and filling it with grease then putting the boot back on? Also usually when a CV goes bad you will notice a lot more clicking during turning. Try it in a parking lot with your windows down and see what you get. Maybe have someone out side try and narrow down where the noise is coming from.
Just throwing this out there but have you checked the oil level?
