Some doctors do this...with steroids.

I think you should ask if this doctor intends to taper you off.
A week, may be okay, but for inflammatory things, a cold turkey ending during an inflammatory event, will really hurt.

Some doctors use a Medrol dospak as a tester. If you have arthritis or allergies, you feel really good for about 3 days, and as you taper off, then it all can come roaring back. But this does reveal a process if you have one, that is inflammation based.

Tramadol works for me, but I don't take it all the time. I save it for really bad nights. I only use 50mg, once a day that way.
I can go quite a while before needing more.
I have increased my Aleve to two at night, because my left ankle has been swelling. I have arthritis and gout which complicate things.

I haven't requested Elavil yet, since my pain is not severe or constant. But I did take doxepin (another TCA) many years ago for sciatica and that worked well.
