Hi !

I'm new to this forum, I'm a 33 years old man from Canada.

I had an ankle sprain 16 years ago and never got rid of the pain.

I've seen hundreds of doctors and therapists, did tons of x-rays, mri, emg, echography, scans of all kind, etc. Results are always negative.

Tried lots of different medications, even dilaudid doesn't help much.


I would like to know if CRPS ALWAYS cause changes in the affected body part like swelling, redness, change of temperature, etc. In my case, I don't have any visual signs, both of my feet look the same. Temperature feels the same too.

My problem is with the pain. I can't stand or walk for more than 30 seconds without feeling pain and after 4-5 minutes I have to sit, like my foot is super sensitive to pressure.

On some occasions (which are starting to happen more often), I start feeling a very sharp burning sensation in my foot. Sometimes the pain can reach 9/10.

I also started doing graded motor imagery (mirror therapy), and it seems to interfer with my pain. Sometimes doing mirror therapy gives me flares up (9/10 pain), sometimes it can make it go away... Maybe I'm doing it wrong.

So like I said, my question is:
Can I have CRPS and NOT have color/shape/temperature changes in my foot and only have the pain component of the disorder?
