is this OCD behavior?!

If I step on a crack in the sidewalk, a line in tile flooring, a bump in the street (driving or walking), or even a change in color or pattern in carpeting, I physically experience heaviness in one side of my body, unevenness, and uneasiness. The only thing is, if I am not paying attention or can't see/feel what I am walking on, I don't experience anything abnormal.

I also obsessively count calories and fat content in foods, which is probably unrelated, but worth mentioning.

Could this be OCD or do I just have some OCD tendencies?
