the main point when you fill out those forms is to describe how fibro and myofascial pain interfer with your ability to work. The disease itself isnt what gets you ssi or ssdi. Its how that disease affects your ability to work. Describe your worst day and dont be ashamed to put down any psychological problems that you have that also contribute to you not being able to work, as well as the effect of medication. i have a listing of impairments somewhere, ill find it later and then post the site here.
