When can I expect to feel better?

I got diagnosed with Lyme based on a bullseye rash and intense joint pain, head aches, night sweats, swollen lymph nodes, low grade fever.No blood work done because dr. Said it’s def lyme.

She put my on 200 mg a day of doxycycline for 4 weeks.

Is this the right treatment?

I’m 24 hours in and my joint pain is outrageous and has increased significantly.

When can I expect to get some relief?
