It is thought to be caused by a severely inflamed and necrotic liver rubbing up against the peritoneum.

Working and SSDI Benefits. Generally, you can't start doing substantial gainful activity (SGA) and continue to receive disability benefits. In a nutshell, SGA means you are working and making more than $1,130 per month in 2016 (or $1,820 if you're blind). There are exceptions to this rule, however. For SSDI recipients, there is a trial work period during which you can make more than the SGA amount without losing your benefits. (For a discussion of how much you can work when applying for benefits, see our section on working and eligibility for Social Security disability.)
It is not based on how severe your disability is or how much income you have. Most SSDI recipients receive between $700 and $1,700 per month (the average for 2017 is $1,171). However, if you are receiving disability payments from other sources, as discussed below, your payment may be reduced. Calculating Your Social Security Disability Payment.
