In this abstract, we present a case report of benign acute childhood myositis secondary to influenza. On presentation, he was ill-appearing, febrile and had significant calf pain that limited mobility. Examination revealed mildly erythematous throat and bilateral calf tenderness with pain on dorsiflexion bilaterally. A respiratory virus panel was positive for influenza A subtype H3 and he was found to have an elevated creatine phosphokinase. He was diagnosed with benign acute childhood myositis secondary to influenza type A infection and symptoms gradually resolved following supportive management. Management involves oral hydration, pain management, and follow-up to ensure resolution. Extensive laboratory evaluation and hospitalization are often unnecessary. Benign acute childhood myositis is self-limiting with an excellent prognosis and should be included in the differential for a child who develops difficulty walking, particularly when presentation follows a respiratory infection. <\/jats:p>","DOI":"10.1177\/2050313x211047321","type":"journal-article","created":{"date-parts":[[2021,9,17]],"date-time":"2021-09-17T13:01:36Z","timestamp":1631883696000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["A crawling case of benign acute childhood myositis"],"prefix":"10.1177","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1006-031X","authenticated-orcid":false,"given":"Alexis V","family":"Hyczko","sequence":"first","affiliation":[{"name":"Penn State College of Medicine, Hershey, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5169-3527","authenticated-orcid":false,"given":"Mary Katherine","family":"Rohrbaugh","sequence":"additional","affiliation":[{"name":"Penn State College of Medicine, Hershey, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alawia K","family":"Suliman","sequence":"additional","affiliation":[{"name":"Penn State College of Medicine, Hershey, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicole M","family":"Hackman","sequence":"additional","affiliation":[{"name":"Penn State College of Medicine, Hershey, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,9,17]]},"reference":[{"key":"bibr1-2050313X211047321","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651-2227.1957.tb08627.x"},{"key":"bibr2-2050313X211047321","doi-asserted-by":"publisher","DOI":"10.12968\/hmed.2017.78.7.410"},{"key":"bibr3-2050313X211047321","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-0691.2009.03064.x"},{"key":"bibr4-2050313X211047321","doi-asserted-by":"publisher","DOI":"10.1111\/j.1750-2659.2009.00102.x"},{"issue":"2","key":"bibr5-2050313X211047321","first-page":"268","volume":"88","author":"Cavagnaro SMF","year":"2017","journal-title":"Rev Chil Pediatr"},{"key":"bibr6-2050313X211047321","doi-asserted-by":"publisher","DOI":"10.1128\/CMR.00001-08"},{"key":"bibr7-2050313X211047321","doi-asserted-by":"publisher","DOI":"10.1007\/s11908-010-0118-z"},{"key":"bibr8-2050313X211047321","doi-asserted-by":"publisher","DOI":"10.1007\/5584_2017_79"},{"issue":"2","key":"bibr9-2050313X211047321","first-page":"95","volume":"37","author":"Hu JJ","year":"2004","journal-title":"J Microbiol Immunol Infect"},{"key":"bibr10-2050313X211047321","doi-asserted-by":"publisher","DOI":"10.1097\/INF.0b013e318191eef7"},{"key":"bibr11-2050313X211047321","doi-asserted-by":"publisher","DOI":"10.1007\/s15010-004-4003-2"},{"key":"bibr12-2050313X211047321","doi-asserted-by":"publisher","DOI":"10.4103\/JPN.JPN_116_18"},{"key":"bibr13-2050313X211047321","unstructured":"Mount DB.
