This sounds like it was exhausting! It's a shame you have to go all over the place. I too am a bit concerned about how they are pushing you. It seemed like for me pushing too hard just caused me to backslide and I kept having to re-approach rehab a little more gently.

If it were me I would probably give it three tries before judging. You definitely have to get them trained! These people don't know you and aren't familiar with your injury. Nerve injury IS different than non-nerve injury and that needs to be taken into account. I personally think it's hooey that your foot is colder because it's trained to be cooler. My Physical medicine doc said that even without CRPS my foot might be cooler the rest of my life just from the nerve injury. That's what happens sometimes.

I do think there is benefit to trying so long as you can find some balance with the program. Even with a nerve injury you can do some re-training and that may help you. I wouldn't tell them you're doing exercises that you aren't. They need to know exactly how you are responding so they can adjust your treatment plan. Take pictures of your foot if you need to.

I hope the amitriptyline helps this time. I got relief from nortriptyline in about two weeks and it helped me sleep better. The sleep aid alone helped me have less pain. Nortrip is a metabolite of amitrip and has less side effects if those are too bothersome.

Can you try a half size larger on your shoe? I had to do that for a long time...

I hope you get relief soon!
