Not sure it's RSD related, but definitely affected by the full body RSD...
My back was hurting between my shoulder blades yesterday (nothing surprising since I've had back problems for years), but last night it just felt worse and it hurt to lean back on the couch. So I reached back to see if I could rub it a bit and found this huge knot right no my spine between the shoulder blades...not a good area. I managed to get my mirrors angled to see it, and it looks bruised and hurts...sharp pain if I touch it. I go to the doctor tomorrow for it...not messing with this. I so wish I had my power wheelchair already cuz it's almost impossible to lean on my cane, but walking has gotten more difficult too. Could be a simple cyst or something like that, but with the way RSD affects bones, there's no telling.
