Bilateral basal ganglia calcification is a condition where large calcium deposits form in the brain, potentially causing movement issues like stiffness and tremors.

Your symptoms, including persistent headaches, facial discomfort, and fatigue, could stem from several conditions, such as sinus issues, tension headaches, or even dehydration. The blood in saliva may indicate an underlying issue that warrants further evaluation. I strongly recommend scheduling an appointment with a healthcare professional. They can perform a thorough examination and possibly recommend tests to identify the root cause. In the meantime, ensure you stay well-hydrated, rest adequately, and note any additional changes in your symptoms.

A spinal cord issue such as hers might result in weakness of stepping and the absence of the sense of touch. It occurs when the spinal cord sustains damage, generally from events such as a car ramming into it. Exercise makes muscles stronger, but full recovery might not be attained.
