Hello Dotty and Smitten and thank you for responding.
Smitten - My GP told me that low iron can cause fatigue, headache, nausea, anorexia ( not wanting to eat ), shortness of breath, cold hands and feet and motility disorder which means constipation I think. Quite a list I think you'll agree and I have them all except headache and constipation. Oddly I felt better able to cope when I thought everything was down to hormones but now I'm really panicking about what the low iron is doing to me. I have never had my Vitamin D checked but I will buy some tomorrow and see if it helps.
Dotty - You have reminded me that I need to report back to the specialist so I will save my pennies and book an appointment in the near future.
Thank you again ladies for reading my tale of woe and I am grateful for your comments.
Wishing you both well.
