So, my work is pretty difficult to work with at times when it comes to accommodations. I already asked for an ergonomic chair as a non-medical ergonomic accommodation, and was denied. I'm having a lot of back pain and really need a different chair, so I'd like to just submit a medical ergonomic accommodation request to avoid another headache, but I need to know what kind of doctor to go to to get the order for an ergonomic chair, as I can't afford to go to several doctors for this, and I don't have a primary care doctor.
