Having a cold sensation in my toes on right foot. feels like blood flowing in my foot. no tingling or numbness. i believe i have experienced this before with having it in one foot. goes away when i walk. had the j&j vaccine on tuesday. im 42?

If you touch the toes that feel cold but the skin temperature feels normal, this would point to peripheral neuropathy as a probable cause. If the skin temperature also feels cold a circulation issue such as vasospasm would be likely. Blockage in the leg arteries would be unlikely in the absence of diabetes or heavy smoking history. It's worthwhile seeing your MD,checking sugar levels, vit B12 leve
