There are people with CH who have obtained SSDI disability. For most, it was a multi-appeal, multi-year process, but I gather that some got it pretty quickly. No kind of headache is specifically covered by the SSDI guidelines. The Budget Director of the Trump administration said just within the last few days that he'd like to see more people thrown off disability (the ones that "don't deserve it," of course). You can get the basics here: https://www.ssa.gov/disabilityssi/ Lawyers who handle disability cases can't charge you, except for basic things like copying, unless you win your case. In previous discussions of this here, some people have said handling your case yourself is the only way to go, and others have said they were glad they had a lawyer. I remember one or two saying they were glad they had an experienced local lawyer who knew the judges who rule on these cases. There are many big law firms that do mostly disability cases. Since it's free to ask, you might consider calling some to see what they advise you. I have figured that because of the payment situation, they might not want to take a case they don't feel confident of winning.
