It isn't good to work (not even part-time)if you are filing for SSDI/SSI.Give them a call. They will want to know about your conditions and what you can and can't do. Do you have documentation about your migraines? Do your doctors say you are disabled? They might not take your case until after you have been denied the first time. Still ,it would be good to call them and see what they say. If you can't work,you can't work.
