Following my post from 3 months ago I must say the springtime has brought huge relief and I am back to normal. How strange this is! Why? Nothing has changed but the weather and we have central heating, wrap up well to go out in the cold. The itching too: no problem now, but I guess it will be back come winter. I do not get depressed in winter so I cannot understand this at all. I take Vit D supplements all year. Perhaps it is the pineal gland? Or maybe I have changed into a tree?
