Personally i would file for disability while you are deciding on what you want to do. It stops the clock so that you dont lose earnings quarters while deciding, and may get you more back pay down the road. Peripheral Neuropathy is listed with SSDI. Its 11.14 The important part is how your symptoms, and medications interfer with your ability to work. I think that you should contact Mike Finkelstein for help in filling out the original application.
Social security has total disability for a condition that will keep you out of work for one year. They dont have partial disability. About 35% of people are approved from the initial application, which is why its important to have someone help you fill out the form that knows what they are doing. Good luck and if you have any questions, ask away.
