I am running 102.4 fever 2 weeks post op augmentation and lift. Is this normal?

See your doctor right away. When your plastic surgeon and or his staff tells you they want to know about any concerns, they mean it. This could be unrelated, or it could be serious. don't wait on things like this.  Don't wait on things.  If your surgeon isn't immediately available see a Nurse Practitioner or a PA in his office. Your surgeon will want to know right away. If you are still suffering and your PS isn't available, see your primary care physician who can take your vital signs or share them with your doctor.  Hopefully this will turn out to be nothing serious but it certainly is nothing to dismiss. 

This is not normal.  You need to see a physician ASAP.  Your PCP or PS are good options.Best,
