Hi MontysMom I'm on the 50mcg Fentanyl patch. I've gone thru the withdrawl before, and It didn't start until a day or two after I had taken the last one off that I had. What you may be going thru is the thought of not being able to get that one to stick back on (anxiety). When you take a patch off, the Fentanyl stays in the skin about 12 hours or something like that so that it gives your next patch time to start working.
I sure hope your doctor got back to you, because if you keep it off too long, you will start having withdrawl symptoms. I wouldn't wish those on anyone.
I had an MRI done, and they didn't have me take my patch off, and I was ok.
Take care. I wish you well.
