This is a loaded question. I guess it would depend on the individual and their situation. I know people who have psoriasis and psoriatic arthritis and get disability. But I also know people who have applied and got denied.
I believe that if it limits your life activities that you would otherwise be able to pursue then yes to me it is a disability.
Are you applying for disability for income or a disability sticker? It would depend on how bad your illness is. Getting a sticker is usually simple, but getting financial help may be difficult.
I would suppose a doctor would have to determine your pain and treatment. They would have to decide if this makes you unable to do any type of work.
What are your thoughts on this? We would love to hear from you.
