At the beginning of this year, I had extreme itching together with several new and serious symptoms like Extreme/internal/generalized itching, extreme weight loss, extreme fatigue, cracked heel, frequent urination and thirst, and several others. At one time I really thought, I was going to die.
I tested for Sugar but was normal.
I started to take Flax seeds. It has helped me a lot with some of the symptoms, though others persist (including weight loss and fatigue; and some new ones have come up, including swollen lymph nodes with pus in them). I think the most immediate effect was on itching, which was gone completely in a few days. It tended to return if I missed taking flax seeds even on a single day.
