Is the something that can be done for caroid artery spasms?

Yes: Calcium channel blockers can reduce arterial spasm.

Workup needed first.: The condition of carotid artery spasms is very rare and needs imaging studies during the event to document it. In general, however, it is likely to be something entirely different (would be more productive to describe symptoms, then presumed diagnosis). Anything to do with carotid arteries requires imaging study - that is what i would start with.
