Everyone has different symptoms. If the foot is cool to the touch and does not go away you might want to have the circulation checked.

I deal with very similar issues. If it's new symptoms, and been a couple of days, it may be a relapse.
If it's a long standing issue, it's just something we have to deal with. None of us know what symptoms are going to bother us on a daily basis. All you can really do is try to rest.
