I thought it might be interesting to put together a list of chronic pain disorders or conditions that result in chronic intractable pain as one of the signs/symptoms.
I write this in response to a commenter (hard to tell if all the comments were from one person using aliases or more than one person.) It is the same old story of defending the reality of chronic pain. People believe when you have other invisible illnesses, like cancer or diabetes. This should be no different but for some it is and that is a shame, for them and for anyone in their lives who suffer with/from chronic pain disorder.
Please feel free to add others.
CRSP, complex regional pain syndrome
Back problems and injuries that cannot be fixed
Arthritis (which can be very severe)
Anaesthesia dolorosa (phantom pain)
Trigeminal neuralgia and other neuralgias of the cranial nerves
Post cancer pain.
Failed surgeries that result in neuropathies that cannot be cured.
