I took my husband to the ER two days ago, he was achy, had chills, fever of 102 (which lasted 36 hours). They ran a bunch of test (flu, strep, CAT scan, XRays, ) found nothing but a slightly elevated white count. Haven't gotten all the blood work back yet. Today he woke up and his right leg looks like he was beaten its, red, black and blue. Swollen lymph node in groin. No trauma to the area. (did have a femoral art. graph in other leg, this leg they took vein from). What is this?
