You are fortunate to have caught it early..and started treatment right away. But, you must treat it with the right dose of doxy and for long enough.
This is your best chance of knocking it out NOW and not have it become a chronic infection.
The doxy should be 200 mg twice daily. You need to treat until you are symptom free PLUS 4-8 more weeks.
Here are the Lyme Disease Treatment Guidelines.www.lymenet.org/BurrGuide200810.pdf
Look at Page 18-20 - you will see the doxycycline dosage, as well as treatment duration.
Print it off if you need to and show your Dr.
BTW - I never had a fever or a headache...or flu-like symptoms.
I would also schedule an appt. with a LLMD for follow up . you've got a lot of symptoms - and you may need more than one antibiotic to treat.
