Nayab,
Staying up with this group and making some contacts here, was and is very helpful for me. It continues to be helpful 3.5 years after my diagnosis. The IVIG has been a lifesaver, and has also helped through the mental/emotional aspects as well. There is a 'new normal' that you and your husband will need to work through. Please don't disregard the mental/emotional aspect. I suffered from some post-traumatic stress following my epsiode and had to seek counseling. I had never felt comfortable with counseling, but endured it as well. It was almost like I had to go through a 'greiving' type of process due to the loss of my 'old self and past life'. It can be done though!
Prior to the IVIG, I had my initial episode that I almost did not survive(the ICU doctor told me at my release that no one there thought I was going to live through it....but was released in 6 days and was fortunate to not have to go through fasciotomies ...although it was close) then I had some smaller self correcting episodes in the following months and then 9 months after my initial episode, landed back in the ICU. That second hospitalization was much less traumatic as we knew what was happening and convinced the doctors to manage the fluids, use Albumin vs just Saline and then IVIG started monthly from there. I have not experienced a symptom since starting IVIG. That is not always the case, I understand, but far and away, most are having very good outcomes when on monthly, full dose IVIG. I am on Ocatagam, but originally started with Privigen.
In regards to your questions: It sounds like your husband is a physician which I am sure will work in his favor. - After my diagnosis, I spent a considerable amount of time networking and educating the Doctors that treated me while in the hospital, just in case I ended up there again. They had not heard of SCLS until I showed them some of the papers and the written diagnosis from Dr. Greipp at the Mayo Clinic. I now have two doctors - a Personal Physician and an Oncologist/Hematologist that I see on a regular basis. Both can advocate for me. I carry information with me at all times on my condition and who to contact in case of emergency. I also wear a Medic Alert Bracelet indicating I have this condition. In regards to passing out - I did not have that rapid type of episode. It would come on over the course of a day or two and my blood pressure slowly dropped. But I understand the concern and was worried about that as well. Others have had the situation where there was not much warning, so maybe they can convey some options for you on that. The IVIG should help to avoid that., but until you have more experience, there may be others to help recommend steps that can be taken.
I wish you and your husband well and can continue to send information or recommendatiosn if you wish.
