After two days of mild improvement, she participated in a local horse grooming show. Shortly thereafter, she deteriorated rapidly with a rash on her left leg, swelling, and a painful limp.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Dual_Diagnosis_Influenza_B_Might_Have_Let_Her_Guard_Down\"><\/span>Dual Diagnosis: Influenza B Might Have Let Her Guard Down<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Initial tests revealed she was infected with Influenza B. Doctors suspended her physical activity and asked her to rest\u2014but blood cultures later confirmed <em>Streptococcus equi<\/em>.

MRI scans of her thigh confirmed micro-abscesses in the adductor minimus muscle and other signs of muscle damage\u2014but thankfully not necrotizing fasciitis. She initially received IV Ceftriaxone, later switched to Benzyl Penicillin, and ultimately Daptomycin (due to a penicillin allergy), administered via a PICC line over six weeks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Recovery_Ongoing_Follow-Up\"><\/span>Recovery &amp; Ongoing Follow-Up<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>By week nine, her blood markers (creatine kinase and CRP) had normalized.
