Thank you. Yeah, it was a herx. Severe rib pain isn't a side effect. The headaches have declined from severe to dull, so that seems like a herx, too, along with the chills and swings in body temp. Now, I'm down to reduced rib pain, mild headaches, and exhaustion.
I've never taken it. I don't think it's given very often for Lyme but it is sometimes.
The people who report what they experienced with it are about the usual mix---- some loved it, some hated it. Some got better, some didn't.
I hope you get better on it. Are you sure it was a herx and not side effects? It's hard to tell the difference.
