I have a rash under my right eye that started a few months ago... my whole face itches at times now. Sharp itch that then becomes painful upon scratching.  My back hurts and when I twist it around my tongue goes numb and Im dizzy / light headed often.  Seem to be in a fuzz a lot of the time.  Whole body itches at times.
HI, thanks for using Chat Doctor Persistent itching can be associated with allergies, liver disease, reaction to medication, kidney disease, infection such as scabies. To determine the cause you would need to visit your doctor for an assessment which would include history and examination. Based on the history and examination you may need investigations such as allergy testing, liver function tests, kidney tests. I hope this helps
