I get dry, flaky skin in my ears and on the back of my right calf muscle. How can I get rid of this?

Depends on cause. Some of the more common causes of dry flaky skin in the ears include a condition called seborrhea dermatitis as well as a skin allergy or skin yeast infection. Your primary care doctor may be able to treat this. If not, you may be referred to a dermatologist.
These are probably.. ..Two separate issues, seborrheic dermatitis in the ears and an eczema of some sort (there are many) on your leg. Hydrocortisone cream, applied twice a day, may resolve both; if not, you'll have to see a dermatologist for a prescription.
