Has anyone tried TMS therapy?

My DD thinks I should consider it for my chronic pain/fibromyalgia - I am on daily pain meds (not depressed per se but have tried various anti-depression meds in the past with zero results) - I wonder whether it’s worth a shot?

I also wonder how much insurance covers - though most insurances do seem to cover it.
