Actually before 2 years I had a itchy spot on my leg and I used an ointment to cure it. After lot of days it get cured and things were normal. But after 6-7 months later I again got such itchy spots somewhere else on my body and at that time those all get opened to discharge sticky liquid (which get yellow colour after drying). I went for a doctor he gave me antibiotics and anti allergic tablets. It worked for sometimes but again after some months I got such itchy spots again. The thing is the places where I got this itchy spots earlier those are the spots again affected and May be some new spots near them. Mostly I got them in limbs (both upper and lower). Actually I have vitamin D deficiency. What is the reason? How to treat it?
