Is CRPS 1 a problem in the central nervous system, autonomic nervous system (sympathetic nervous system) or is the condition a mix of the whole nervous system?

Also, could each individual have different parts of the nervous system compared to others? Just the sympathetic NS for example?

I have had CRPS 1 in my loweg right leg as a result from an overuse injury resulting in a soft tissue strain (hamstig tendon) for 6 months. Just wondering if its possible to determin which part of the nervous system is effected in my condition?

Reason im asking is because I do not have every symptom that comes with CRPS (pain to touch) however i have alot of sympathetic pain (abnormal temreture change, burning pain & redness of the feet). Also wanted to know if ketamine IV treatment hits all angles in regards to treatment for CRPS?

Thanks for any help,

Nigel
