When I sit for to long my feet start to go numb I am under the impression that this is poor circulation what can I do to improve it.?
May not be. Although circulatory problems may cause the symptoms you describe, you may also need to consider that sitting for a long time in the same position may be producing a compressive neurovascular problem. That is, sitting may be pressing on blood vessels or directly on nerves that then give you the sensation of numbness. Changing positions, chair, adding a pillow, or getting up often may solve it.
