Group B streptococcal endocarditis presenting with bilateral trapezius myalgias.

I describe a patient with bilateral trapezius myalgias as a presenting manifestation of group B streptococcal endocarditis. Diffuse myalgias occur in association with bacterial endocarditis. However, localized trapezius myalgias have not been reported. Physicians should consider the diagnosis of endocarditis in patients with this compliant.
