I'm on disability with Fibromyalgia Chronic pain and my doctor, physiotherapist, Chriro and massage therapist recommended a infrared therapy blanket device. I was wondering if my disability covers that or a part of it?

You can review your LTD policy to see if there is any section that includes a mandate to supply rehabilitation supports. Unfortunately, they don't usually have that obligation, however some insurers may still be willing to help with costs. The best way to know is to ask your case manager directly if they'd assist in this situation
