ADDITION TO ABOVE: My toes are also not hypersensitive to touch (thankfully). My CRPS reaction happens after 10-15mins of walking then, 1. heat, 2. redness, 3. swelling, 4. pain. Then I put my feet up by lying down, and it all calms down again. Pain, redness, heat, swelling all dies down and stops.

The Amitriptylene extends the period before triggering the reaction, and the redness and swelling doesn't go up so far, but still as bad in the actual toes.

I have now got two appointments booked for this coming week with CRPS specialists and I'll report back with what they say and suggest.
