My original thread has become a little long and unwieldy so I thought I would start a new thread. I saw the doctor this morning and my Vitamin D level is 12, i.e. through the floor whichever definition of normal you use. I will continue on a loading dose for a few more days then go onto a maintenance dose thereafter.
Considering Vitamin D is important for bone and muscle strength, so important for my ongoing rehab, I am glad I raised the issue!
