Welcome and thanks for posting your query to HealthcareMagic.
As per your query you have spider angiomias all over the upper body and is not able to find out the cause of the same.
Spider angiomas are characterized by central red spot and reddish extensions which radiate outwards to look like a spider's web. They are caused by significant hepatic disease, or in women using hormonal contraception
or also by increased estrogen
levels in the blood.
IN yourself the liver
functions are normal and you are not using any contraception also. So just go for the hormonal tests especially estrogen related. If these are normal then you are also a part of normal population where we find these without any cause and there fore not a thing of concern.
Reduce your stress
for the same as I can get you have bit itching and burning which is not at all a feature of this problem. So stay calm and go for hormonal level- if normal then relax!!
I hope these information's will help you. If you have further queries I will be happy to help.
"Wish you good health"
