I've just been diagnosed with a severe Vitamin D deficiency after asking for a test. I wondered if anyone here had had experience of this and how they felt after taking the supplements - been given 100,000 iu to take over three days. Feeling slightly aggrieved as I have been visiting the GP for three years with fatigue, low mood, brain fog, weight gain as well severe psoriasis on my hands and feet. At different times I told them that my job was very busy over the summer months. I went in March last year and specifically asked for blood tests as I was literally dragging myself into work each day and was not coping. Received the results over the phone and was told everything was normal, but, unknown to me, I hadn't been tested for Vit D. So, I handed my notice in and left work in July. By December I still felt exhausted etc so went to the GP in January to check whether I was deficient, ask for a referral for light therapy for my psoriasis and also a referral to a counsellor because I still felt low. Discovered I hadn't been tested, had it done, waited two weeks for the results then received a letter asking me to come in as I was deficient - I had hardly any, less than 12 iu. Ten days on from taking the supplements my psoriasis has very nearly cleared up (for years I had so many cuts on my hands that they were covered in plasters) , I feel brighter and happier and am now tackling the jobs around my house which I have felt unable to do during the past six months, which is fantastic. However, I am unhappy that I had to ask for the test despite having many symptoms and my inability to function at work led me to hand in my notice. I have funds to live on currently but will need to work in the future. I will at the very least speak to the Practice Manager about this, any thoughts or experiences of similar situations?
