Unfortunately RSD doesn't run it's course it is with you for life, some who have been given good treatments early enough have gone into long term remission, I've read of one who was able to lead a normal life for 10 years before it came back but it does.
If you don't well I didn't get to see a specialist until 1 year and 11 days after it started,he said because of the wrong treatments and delay there was no chance of ever getting remission.
Under no ccircumstances should you allow the use of Ice or Hot and Cold Water Contrast Therapy these can and have caused severe blood vessel damage. Nr should you allow aggressive Physio this will prevent remission and is likely to cause it to spread.
