What could cause a sudden itchy rash all over body?

I woke up last week with an itchy rash on my stomach, back, legs, arms and neck. it started as tiny little red pin prick sized spots that have grown bigger, some now oval shape. They are pink. It is everywhere except soles of feet, hands and face. I have been to the doctors twice and they gave my cream for eczema and antihistamines, none are working. It looks like it is spreading/becoming more irritated. It is really itchy and when I am dressed it feels like sunburn/sandpaper.

As far as I am aware, I have no allergies even though one doctor said it could be hives but it does not look or sound like the symptoms of hives.

Any advice or comments on what it could be and why it happened so suddenly will be greatly appreciated. Thanks.

Hello and welcome to ehealth forum.

Based on your history, it does appear to be acute urticaria. Its been a week so you should continue the antihistamines for now. Ideally, based on the specific presentation , mebendazole and antibiotics can also be advised. Triamcinolone IM can be given for prolonged relief if the itching and rash doesnt subside.

I hope this helps and wish you good luck
