I'm dealing with a burning sensation all over my body and it feels like nerve pain, with pins and needles, and sometimes it feels like a heat wave inside. I've also got nerve pain in my jaw. I've been told I might have Complex Regional Pain Syndrome by one doctor in NZ, and a neurologist mentioned Central Pain Syndrome. I'm really concerned and a bit confused about these diagnoses. Could you explain what they mean and how they differ? Also, what can I do to manage or reduce these symptoms?

Approximately 80% of patients with CRPS type I achieve complete, spontaneous relief of signs and symptoms within 18 months; however, no diagnostic criteria have been shown to predict which patients will fall into this category. Some of the patients whose symptoms do not resolve spontaneously may still be cured by treatment. Of the patients who develop refractory CRPS type I, 50-80% have disability secondary to pain andor a limited range of motion. The main disabilities are limitations in their activities of daily living (ADL).

I've been noticing this strange warm sensation in my lower leg lately. It pops up for about a minute then just disappears on its own. There's no pain or swelling, just feels like heat is leaving that area. Occasionally, I'll feel it in my back or shoulder too, but it's pretty rare. Could this be linked to having had Covid a couple of months ago? I had my d-dimer checked back then and it was normal. What might be going on with these sensations?

The intermittent, brief, and painless warm sensations in your lower leg, back, or shoulder could be due to various benign causes, such as vasospasm (temporary blood vessel constriction), nerve sensitivity, or muscle relaxation, and while it's reassuring that your D-dimer levels were normal after COVID-19, it's still possible that you may be experiencing post-COVID-19 symptoms, such as autonomic nervous system dysfunction or peripheral neuropathy, so consulting a doctor to rule out any underlying conditions and determine the best course of action is recommended.
