The medical term for 'chicken skin'is pilaris Keratosis.
I didnt answer because I don't know. Some people use this term to refer to severe sun damage. This is called, "Poikiloderma of Civatte." Others use it to refer to a genetic condition called Ehlers-Danlos Syndrome. None of my huge dermatology textbooks have an index item, "chicken skin," and a Google search got me record companies.
Would it be out of line for me to suggest that you ask the dermatologist who examined you what he or she thinks it is?
Best.
