Dear Silje,
Are you getting the recommended dose of IVIG? My attacks didn't stop completely until I got the full dose of IVIG. Also, after a few months of being on the full dose, I would get minor attacks towards the end of the month because the medicine would start to wear off before my next infusion. In May, I went to every 2 weeks, getting 1g/kg at each infusion, for a total of 2g/kg each month. This was because of minor swelling, not feeling well towards the end of the month, and also because I was prone to aseptic meningitis from getting all the medicine at once. I was on high doses of prednisone to try and prevent it for a long time and still getting massive headaches. Since going every 2 weeks, no more minor attacks and no more prednisone. I still feel tired and nauseous after my infusions and get a slight headache, but nothing compared to before.
Also, I had major abdominal swelling when I had attacks. My stomach was my most problem area. I did have a lot of swelling in my extremities, but my swelling was not limited to those areas. Everyone is different and every disease can present itself differently in each person. If every disease was text book, everyone who was sick would be easily diagnosed. There is no definitive test for SCLS, it is a disease of exclusion. Also, you have capillaries everywhere in your body, not just in your extremities. This might just be where your body is prone to leak.
Don't get discouraged, sometimes it takes a while to feel better. Your body has been thru a lot. I thought I would feel back to normal after I started my treatments. I have finally come to the conclusion that I will never feel my old normal again. I do have a new normal though. Not a perfect normal, but way better than it used to be :)
I really hope things start to get better for you,
Maria
