In your research of the SSA website did you look at & study the SSA definition of disability? Just because you cannot perform your work as an organist does not mean you cannot perform ANY type of work. In determining that you do/do not have a medical condition so severe that it is expected to result in death, or be so severe that it has lasted, or is expected to last 12 months and prevent ANY type of work the disability determinations office will look at your age, education, past work experience and overall medical condition.

There is an expectation that you would not have surgery if you did not expect it to improve your ability to function. A determination will probably not be made until the effectiveness of the surgery can be assessed. If you are under 50, have a high school diploma and past work experience back/neck problems are seldom considered disabling enough to meet SSA standards.

Diabetes type II is usually not disabling but your case may be different. What caused the stroke? Was it the diabetes? What are the residuals? Can you walk/talk, etc, or are you paralyzed on one side? How bad is the neuropathy? Can you walk, feel your feet, etc.? How does the polycethemia vera affect your ability to breath, how severe is the dizziness & how do these conditions affect your ability to function.

Statements from your treating doctors identifying each condition with treating documentation as to how the conditions affect your ability to function will be most helpful.

Information documenting a medically diagnosed condition & how that condition affects the ability to perform work related functions will not be overwhelming.
