if you get the short form, only check the answers for the questions asked. dont write in the remarks section at the end.
when i did mine, the quesiton for the last three doctors visits, i put the visits that had to do with the illnesses i receive ssdi for. so i just wrote the date and what i went there for. for example 12/14/14 Peripheral Neuropathy
that s it. dont write anything extra, dont attach anything. dont have doctors send anything in.
the long form is where you must go into greater detail. writing anything extra on the short form will lead to it getting kicked out by the computer and a possible long form review.
