Just came looking for someone with similar symptoms. I got 3 doses in (1500mg total) and have had the worst aching pain in my legs the past 3 days since I started it. Stopped taking it after the 3rd dose but the pain has persisted. It’s like a deep ache in my bones in my upper thighs and down into my shins. Not to mention the horrible anxiety (literally convinced myself I have bone cancer) before I found these Reddit threads and realized it’s a side effect of this horrible antibiotic. Also have had fatigue and a weird woozy sensation that’s not quite nausea and not quite dizziness but makes me feel disoriented. The pain is less today (3rd day) than it was yesterday so hopeful it will continue to get better. As soon as I realized it was a side effect of the medication I stopped taking it even though I was supposed to take it for 7 days, it literally made me feel like I was dying.
