CRPS is different for everyone. I dont have major swelling and the discoloration is very minor. I get a re and white mottled color and even then its light. Also the temperature change is sporadic. but the pain you described sound exactly like CRPS I am sorry to hear that your going through this. It could be a Peripheral Neuropathy or just nerve pain in lamans terms some neuropathies can mimic CRPS. I would make sure you see a very good neurologist and go from there. But DONT be silent about your level of pain. Make sure they treat it. You have a very hard road ahead of you....either way you have a life altering diagnosis. Good luck! And know we are here for whenever you need a supportive ear. No one can understand the pain we have except people like us.
