In the few weeks I have been using this site it has been an eye opener and has provided so much useful information for me that I don't know how I would be now without it. I had a blood test after reading up on here about symptoms, found out I was very deficient in Vit D (but full up with Vit B12 as have 3 monthly jabs so just top-up daily on that). I took a huge dose of Vit D and followed that with a daily dose, plus started Magnesium as I read on here that it can be an important factor in feeling better. I also have started Vit B9 as my folate was way down and I have to say I do feel loads better - no brain fog, more energy, sleeping better, less joint pain. But my feet are so painful today that walking is uncomfortable and I am hobbling around?? The Plantar has slowly improved but today it is the soles and outside of my feet that really hurt. I just wish I knew why - it doesn't seem possible that this is to do with the Thyroid and yet I have read (but not remotely understood) the connection with Plantar. So - what now???
