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.)
If you are younger than full retirement age, there is a limit to how much you can earn and still receive full benefits. If you earn more than $15,720 (in 2016), Social Security will deduct $1 from your benefits for each $2 you earn over the threshold. In the year you reach full retirement age, you can earn up to $41,880 (in 2016) without having a reduction in benefits. However, if you exceed $41,880 in earnings, Social Security will deduct $1 from your benefits for each $3 you earn until the month you reach full retirement age.
