If you are itching, there is more to the story.  There are other parts to the history and physical to investigate.

Any new cosmetics or creams? They can cause allergic contact dermatitis, hives or even sensitivity to the sun.

New animal exposures?  Did they give you fleas? or an allergic reaction?

New medications, supplements or illegal drugs?  Hives can occur– or something called fixed drug eruptions.

Contact with sick people?  Let’s hope your vaccines are up to date.  You could have mumps, chicken pox, scarlet fever, fifths disease (the virus that causes cheeks to look slapped), rubeola, or folliculitis (an infection around the hair follicle shaft).

Unexplained weight changes, feeling hot/cold when others are not, changes in menstrual period?  This could be thyroid related and blood work will reveal it.

Unexplained weight loss with night sweats/fever and fatigue?   You also need blood work to rule out a cancer.

Nausea, “bone tired,” less urine output?  Blood work will show if you have kidney failure.

Recent travel?  A good skin exam may reveal lice, scabies, or hives.

A thorough history and physical is the detective work needed to help diagnose (and then cure) itching.

Hope this helps.
