All veins collapsing for blood tests,any suggestions? why does this happen?
A doctor has provided 1 answer
Veins/blood drawing: I would recommend that you hydrate yourself before your next blood draw so that your veins will be dilated. Also, keeping the area of the vein to be used warm will keep it dilated. Veins tend to constrict when dehydrated or in colder weather.
