Do you ever feel this tingle, numbness when you first get up from sitting? If “Yes.” it could be sciatica from the lumbar spine or piriformis deep in your gluts. Do you have diabetes or hypoglycemia? Then it could be neuropathy. Do you have spider or varicose veins, or cold feet? Then it is most likely poor circulation. Get your blood pumping with sun salutations. Listen to your body when it talks to you; don’t feel you have to push through it when this or anything else annoys your body.
