Hello,
I agree with those that have said wait until you have a thorough application. Having multiple conditions and illnesses is to your benefit. Combined they equate to a qualifying condition. There are a number of things you need to do before applying:
1) Get copies of all medical records: office visit notes, imaging and surgery reports; including any psychological or physical therapy specialists
2) research your illnesses on line so you have a through understanding of symptoms that contribute to your inability to function at a job. Even IBS has symptoms that can prohibit working. Kept in mind that means even sedentary jobs.
3) Include all illness that you have no matter how insignificant you think they may be (asthma and allergies are examples).
4)The 2010 application only allows you to list them, not describe how they effect your ability to perform work duties. Example: cognitive impairment for you is a big one. ( It includes loss of higher reasoning, forgetfulness, learning disabilities, concentration difficulties, decreased intelligence, and other reductions in mental functions.) AS a result of the symptoms your ability to handle stress is decreased. So, you need to add an attachment that describes the symptoms of each condition and specify how the symptom effects your ability to work. Use adjectives and measurements. Example: Due to the excruciating pain in my legs I can only walk a block or climb 10 stair steps.
5) Do not allow your doctors to dismiss your limitations that disable you. Doctors don't determine disability only SSA does. Ask them to document in their notes your limitations. Then, ask them if they would support your claim for disability. If they don't find a new doctor.
6) With cooperative doctors ask them if they would write a letter to SSA listing your symptoms and limitations.
It takes time to prepare a through application, but it is better than waiting year to get your benefits.
