I've had severe dizziness since rhinoplasty/septoplasty/turbinate reduction and chin implant in Jan. Doctor doesn't know why?

After the surgery I took Keflex 500 i did not like the way I felt. It cause a lot of dizziness and anxiety. I’ve had severe dizzyness since fatigue, Heart palpitations. I have gone to my follow up and doctor says this has nothing to do with my surgery. I’ve had lab work down, ct scans, etc and everything seems to be ok. But my dizziness is still there. Do you think this was caused by the surgery?
