Sinus headache, cough, fever one week ago, am on rivaroxiban , asa allergy what pain meds can i use?

Go see your doctor: Rivaroxaban is a blood thinner w/over 300 drug-drug interactions, most of which are moderate or major (http://www.drugs.com/drug-interactions/rivaroxaban.html). Your clinical findings section also lists advair ; dilantin, so any additional medications must take into account interactions w/those too. Go see your doc rivaroxaban vs Dilantin issues. Then ask about pain options. http://goo.gl/wgpwu2.
