Hello, my son, age 24, was assaulted three weeks ago and suffered blunt trauma to his eye. He has had two surgeries since, most recently last Wed. He was taking 40 mg of prednisone prior to the surgery and 60 mg. of percocet for pain pre-and post-surgery. After the surgery, his eye doctor said to taper off the prednisone over four days (20, 10, 10, 10 mg.). He has felt bad for three days...headaches, fatigue, etc. Could it be prednisone withdrawl? Rebound headaches? He is trying not to take the percocet for fear of the latter and is trying extra strength tylenol instead.
