Severe itching x3wks. no rash, bites and previous dry skin now is very moisturized. no meds, started fish oil and lotion for exzema, not helping?

Generalized itch: Generalized itching without primary skin rash most commonly caused by dry skin. Most severe during the winter months and in older people, characterized by itching in areas of dry, scaly skin. Lab work should be checked to see if there is an underlying cause: CBC/diff, liver/renal function tests, and thyroid workup since you seem to be well moisturized.
