Red itchy spots on legs back arms and chest

I'm a 21 year old female and i've been getting this red spots/itchy patches all over my legs, arms, back, chest and sometimes my neck. I try not to sctrach them but they are really itchy. I have longish nails so when I do i get red patchs like a rash all over! I've had this for the past 2/3 weeks and it just keeps getting worse. I don't want to go do the doctor as it's really embarrasing for me. I really don't know what to do to make it go away. Can anyone please help??

This discussion is related to very itchy red blotchy rash on torso, legs arms, back, and neck.

These can be due to hives. Hives (medically known as urticaria) are red, itchy, raised areas of skin that appear in varying shapes and sizes. They have a tendency to change size rapidly and to move around, disappearing in one place and reappearing in other places, often in a matter of hours.

Many cases of hives are "idiopathic," meaning no cause is known. Others may be triggered by viral infections or medications.
I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
