Does raynaud's get worse as a teenager ages?

Not always: The raynaud's and scleroderma association in the U.K. States that raynaud's disease is more common in teens and young adults, especially teen girls and young women. The majority of patients resolve their symptoms in their twenties. (probably the approximately 10% of cases who have secondary conditions causing raynaud's will continue to have symptoms unless their secondary disorders are resolved.).

Maybe: Raynaud's disease might get worse or it might stay the same. There is no fixed pattern; it depends on whether there is another disease causing the raynaud's. If the underlying disease progresses, symptoms of raynaud's may progress with it. If there is no underlying disease, symptoms may remain the same.
