I was diagnosed with a bacterial infection six days ago and injected with Levauin, followed up by 500mg/day. The morning after the injection, my legs started aching as though I had run a marathon, particularly my shins, calves, ankles. Today, I woke up in more pain than before and am starting to notice knots in my shins. Every step is becoming more painful than the next, and I don't know how to fix this. I stopped taking Levaquin yesterday, but this problem keeps getting worse. Has anyone else had this experience, and when do the knots go away and the pain cease? Thanks for any info.
