My dr wrote a script for it at my last appt almost 3 weeks ago.. but my back had been doing much better so I hadn't bothered to get it. It started hurting again yesterday though so I figured I better go get it today..
Of course I went to the crappy pharmacy/medical supply store right near my house so they only had one option and the lady who "does the insurance" is only there M-F so I just paid cash and they'll reimburse me if my insurance does cover it.
I put it on as soon as I got home and honestly I do notice a difference right away. I don't think its something i want to wear all day every day but I think I'll use it for work at least.
