Hello Julie,
Unfortunately, SCLS is just that, a Syndrome, not a completely defined single entity. The essential triad includes hypotension and haemoconcentration; oedema; and hypoalbuminemia. (refer Kapoor et al, (2010); Rabbolini et al (2013); Druey et al (2015)).
Without a fuller picture of your personal condition, it is hard to help, and herein lies one of the major difficulties. In Australia, most ED notes and ICU notes are written on A3 or bigger paper, and irregular sizes. This makes it hard to collate notes into the total picture. X/Ray, and Blood test notes are easily assimilable. I suggest it would be in your interest to request copies of all your tests ASAP, and on an ongoing basis; and obtain full copies of your inpatient notes, - not just discharge summaries.
Now, armed with a full picture, you can make contact with Dr Kirk Druey at the NIH, Maryland, (even through this site) as his experience is valuable. If French is your bag, then Dr Amoura at the Pitie-Salpetriere Hopspital in Paris published the European registry results in 2011.
There is an adequate differential diagnosis list in Druey's review of 2010, which may be an interesting starting point.
If you wish I can send these publications, - you may have them?
John
