Well, your circulation may change from time to time...or during the day.

When you were tested, it was fairly okay...meaning the vessels were open. They might constrict, due to low magnesium levels or poor nitric oxide production, then open again later. Fixed issues due to blockages would remain closed up however, such as plaque deposits.

Your blood may be thick and can't circulate well at the capillary level. The red cells may be too large (from low B12) called macrocytic anemia. A raised MCV test indicates this.

You may have too much triglyceride in the blood, thickening it.
Studies have shown that eating too high a fat content in one meal can slow circulation for several hours. You may have proteins in the serum from cryoglobulinemia:

This will slow the blood flow. Once slowed down, nutrients cannot get in and waste products cannot get out of the peripheral areas properly.

So you need to go back and look at your tests, to see what your blood work said and which tests were done.

It gets complicated, that's for sure.
