A little about myself first. Age 49, paid into SS since 17 or 18 years old and currently working for 13 years with same company. I was diagnosed from my doctor with, 100% cartilage loss (MRI), bursitis and arthritis. As of right now one option is knee replacement, but unlikely to have it done due to funds. Before the MRI the doctor gave 2 options. I have also had every kind of injection possible.

1-knee replacement
2-possible SSDI. Sounds like he would support me.

My primary doctor is also treating me.

I do retail work, but its getting impossible to walk, stand, sit or lay down for short times or long times. I fell at work (knee gave out) and have been demoted as a result.

Should I apply for SSDI? My husband got SSDI several years ago due to being legally blind. The SSDI system looks as if its changed some what.
