Do cold feet + hands always mean poor circulation? post covid im having tingling & cold feet + hands especially when going to sleep. my feet are always very white & cold & i have thalassemia. this is 2 wks post covid would it show on pulse oximetry?

Not always. The body has a protective mechanism that can shift circulation from the body surface to the deeper tissues, primarily to prevent heat loss. This is often marked by cold extremities. That feature can become activated by other conditions unrelated to poor circulation or hot/cold environments. Oximetry is not always helpful in assessing this issue.

Some people have residual symptoms and the relationship with Covid is being worked out.

Your cold feet may also be partly caused by anemia. Also pulse oximetry is often erroneous when vasoconstriction causes cold extremities. Your poor circulation is not caused by peripheral artery blockages but by reflexive constriction of arteries & arterioles in hands and feet in response to cold. If your hands& feet don't feel cold when you touch them, a peripheral neuropathy could be the problem
