Hospital admission.: The patient should be admitted for close observation. Radiology consult for additional testing to be considered, as the pain may be referred and the chest has also been evaluated and a biopsy has been done, without specifying where and why. Certain viruses can give painful contraction of abdominal muscles, to be considered in the differential diagnosis.
