I m 7 1/2 weeks after bilateral knee replacement surgery. Use to take Dalaudid 1.5 mg. ,4 to 6 times daily for about 4 weeks, after which reduced Dilaudid to once or twice a day and Tylenol 3 for the rest of the day. This Dalaudid cut down I did for about 2 weeks. As for the last 2/3 weeks I ve taking Dalaudid once every 4 to 5 days and Tylenol 3 3 to 4 times a day.In the past 3 days I cut the Tylenol to once a day and my last Dilaudid intake was 4 days ago. In the past 7/8 days, I ve been feeling very restless, especially in the evening and at night, with strange unpleasant feeling on my legs, more so around the surgery areas and to my feet, I m also very irritable and anxious . Please tell weather these are withdrawl symptoms and if yes, to which one of the 2 medications and what can I do to help myself feel better. Thank you.
