Hello,
Since three days you have mild temperature and
fatigue, it can be due to over exertion,
stress (emotional / physical), etc. Take rest and stay well hydrated. Take adequate sleep and home made nutritious food to restore your body electrolyte system, blood
glucose, blood pressure and other vitals. You have already taken a flu shot. You should be fine soon. To get rid of mild fever and chills you can take
Acetaminophen, one SOS when required. Take medicines after food. Since you removed ticks out of a dog, tick bites may cause flu like symptoms. If your symptoms continue, get clinically examined by a GP, to rule out
Lyme disease, etc. You will be treated accordingly.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
