This tells me that she has been eating something with chemical or heavy metal ingredients in her food!
(What did she eat at school?)
The body is trying to reject the toxic intake. Take ขมิ้นชัน two capsules after meals for three or four days! Put ขมิ้นชัน on her body to reduce the inflammation!
Take a bath with ขมิ้นชัน.
No need to take skin test, it does not tell you what causes this rash outbreak. Don’t take western medicine, this will suppress the spots and they will go inside the liver. I think she has been taking too much western medicine and steroid too!
If you continue to let the child take lots of chemical medicine, her body will get weaker and her liver will suffer in the long run!
My niece used to have lots of rashes and took lots of pill for the cure! The rashes would go away for 2-3 weeks and they came back bigger! In the end her liver suffered several years later. Not a good ending!!
You depend on western medicine too much!
Search local wisdom and traditional Thai medicine. Some can be useful too.
Drink some อัญชัน tea to cool down the itchiness.
No more รสดี in her food. รสดี contains more than 50% of MSG plus other chemicals!!
(These rashes are reaction from inside the body.)
I may be wrong, but I only speak from my life experience.
