If I had my first appointment over again, I would have taken a list of childhood illnesses, and later ones, with me. Turned out childhood polio was major factor. Other illnesses could impact on LD.
I would also DEMAND proper skin care; UK very bad about this, but it's automatic in most European countries. If you have itchy, flaky skin, you have right to obtain Flexitol Skin Balm and Heel Balm on prescription (most GPs have no idea skin care is so important - and both products are mentioned in BFN)
Others in this forum are much more knowledgeable, so listen to them - and good luck,
