By looking at information you I could not find whether you have bitten or licked by dog. Anyway if you dog is doing fine and not showing signs of Rabies
then it is unlikely that you are having rabies.
Comming to your problem fever, nausea
can happen in other illness like any infection with bacteria or viruses.
I advise you to visit doctor and find out cause of your symptoms, mar require investigations and x ray
Hope you find information useful. Take care
