Does anyone know if there is a link between hypothyroidism/thyroid problems and trouble with blood being taken?
I have trouble every single time, and have done for as long as I remember. Having blood taken can take up to 10 attempts to get any.
I know they shouldn't persist past 3, but it never comes out within 3. So I let them carry on so I can at least have it tested.
What I was wondering is if there is a link between my thyroid problems, poor circulation, adrenal problems etc. and this problem?
If not, do you know what DOES cause it?
