What symptons would you have from RA in the head?

Rheumatoid Arthritis (RA) can cause symptoms in the head primarily through inflammation of the temporomandibular joint (TMJ), leading to jaw pain, difficulty chewing, and headaches. Patients may also experience fatigue and cognitive issues, often referred to as "brain fog." Additionally, inflammation can affect the blood vessels in the scalp, potentially leading to localized pain or tenderness. Overall, these symptoms can significantly impact daily activities and quality of life.
