It's not that simple. Damage at C4 can affect any part of the body connected at or below C4 (because all those nerves go through it). For example, my largest lesion is at C2 and I have paresthesia over my whole skin, not just my head.Cholderby wrote:C4 control the biceps and deltoids, is that where you would expect to find symptoms?
I have the impression that cognitive problems don't usually show up until you've got a decent percentage of brain matter demyelinated...*Do I really have no symptoms from these or is this why I can't remember where I put my car keys? Or perhaps there is so much brain matter there at present that cognitive symptoms won't begin until I've lost more frontal cortex ground. Thoughts?
