I can only answer from my own experience. I am currently on disability due to my PsA because it has been adjudicated (had to go all the way to a judge) that my disease limits me doing the kind of work for which I have been trained to the degree I cannot realistically be expected to consistently earn over $1,000 a month. I was in the military, and when I got out I worked in carpentry. Needless to say, PsA negatively impacts my ability to do nearly everything carpentry related. Whether or not you "qualify" for disability depends a lot on what your previous job experience is; do you have training and/or experience in another field that would be less limited by your disease? What kind of allowances could be made for your current condition that would enable you to work? What vocations are out there that you could be retrained for that you could realistically be expected to take on and earn a living within the limitations of your disease/condition? The first time you apply for SSD, you will be denied. Then when you appeal, you may very likely be denied. Following this, you can request a hearing with a judge, who will have at that hearing a medical doctor and a vocational specialist to help in the decision. So, your best bet is to simply hire an attorney who specializes in disability law. They will get a percentage of whatever back pay you are entitled to, but many states actually place a cap on the amount/percentage they can claim. But it's worth it if it ensures getting approved. Even then, your case will still be subject review on the five year anniversary of when your disability was found/decided to have started (not on the date you actually got approved), and every five years thereafter for awhile. So, keep good records, both medical and work, keep a very specific daily journal of symptoms and how they limit your daily activities and ability to do everything every day, and hire an attorney.
