There’s also a symptoms chart, showing a good comparison of:
Compressed Cervical Spinal Cord, and
Fibromyalgia/Chronic Fatigue Syndrome
It mentions ‘Dysesthesiae’, the burning pain, lower down the list. I think you will see that many of the symptoms listed there are similar to those suffered by EDS people, even though EDS (and Dysautonomia) aren’t the specific conditions mentioned.
The lacy vascular pattern on your arm looks like it a light dose of ‘livedo reticularis’ to me, tell me, does it go away if you warm up the arm ? Have you been checked for Antiphospholipid problems, it might be worth asking your doctor to check ?
