Post op advice/ the flu

so I'm now 15 days post op and I started feeling crappy yesterday. Now I have flu symptoms. My jaw is killing me, head hurts, I'm cold then im hot and im so nauseated. 

Mi took some tylonal cold and flu liquid and it helped with something's but I'm now lying on the couch because the nausea is so bad.

is there anything else that has worked for anyone?

Add in some gravol for the nausea.
