My sister needs us! Carrie recently suffered from carbon monoxide poisoning at work which lead to a very rare condition called RCVS. RCVS stands for Reversible Cerebral Vasoconstriction Syndrome. It's a neurological condition characterized by sudden, severe headaches, often described as "thunderclap" headaches, caused by temporary narrowing (vasoconstriction) of blood vessels in the brain. While often benign, RCVS can lead to serious complications like stroke if not diagnosed and treated promptly. Carrie has had multiple admissions to the hospital because of this and much of the time she was without insurance. Please consider a small donation so we can help my sister.
