@mrea what is the nature of the pain? Is is in one spot, like the bottoms of the feet, or all over? Is it bilateral (both feet) or just one foot? Your doctors should be asking you these questions. If it is bilateral it is, most likely, generated by the spinal nerves and a possible nerve pinch. It could be a sciatica (which is actually a symptom, but involves pinching the nerve either where it comes out of the spine or at the piriformis muscle (I have some sciatica)). Google the “dermatomes” and pain and you’ll see the pain might come from far away. Is it burning/tingling or electric pain (nerve pain) or a duller ache (more often muscles, etc.; different cause entirely - often myofascial pain). These are questions to ask / things to research. Stretching and exercise can help some of these conditions as can diet and adding supplements. I was able to get off nortriptyline with the right program (see my comments to others in this thread for specifics). Also, you most likely have pain sensitization going at this time which amplified the pain. Dr. Jonathan Kuttner has a book called “life after pain”. It is very readable. He also has various courses he offers affordably about how to retrain your pain system on his website “life after pain”. His techniques might help you dial down (and possibly eliminate) the pain. Good luck.
