Summary
A Reddit user with chronic Lyme who takes antibiotics reported being ill since the end of August 2025 with shortness of breath, wheezing, chest fullness and exhaustion. A few hours after starting metronidazole (Flagyl) 500 mg twice daily for seven days in late December 2025 they felt awake, called it a shock, and said they would know as the week unfolded whether the effect lasted.
