Is it this:
Hantavirus Pulmonary Syndrome
Those are the medical acronyms I could find for HPS.
Nevertheless, evaluation of back pain
is helped with a history and physical exam. In children, often times back pain is usually due to "muscle strain", such as in children that carry heavy textbooks in a backpack -- such muscle pains are usually worst over the first few days then get better over a couple of weeks.
Usually, the back pain will improve over a few days and no specific testing is usually necessary. However, back pain that persists, or is associated with other clinical findings (such as fever
, weight loss
, pain that keeps him up at night, pain that travels down the legs, other neurologic signs) needs to be investigated with imaging and further tests.
