Thanks for all your support, Neil and I really appreciate it - he's been as affected by all this as me from an emotional point of view, and your support means a lot ...
I got out of hospital on Saturday with a platelet count of 252

Dropped a little from Friday's 285 (which Neil told you about) - guess could be due to the 2 units of blood I had transfused on Friday night (apparently it can do that - more of why I needed that in a moment!), or could be things stabilising quite quickly - am not going to be pessimistic and think my count is falling until we're a few weeks down the line as my body's been through so many treatments in the last couple of weeks, who knows what's going on! I have another blood count tomorrow so will have an early indication then, anyway. I feel so much better, and improving every day - just been for a 2 mile walk in the park! I have 3 small scars which are healing nicely, and am only slightly tender in my abdomen now so have reduced the painkillers to just paracetamol (that's Tylenol in the US, I think?) - am going to be sensible about my recovery and take it very easy, not allowed to drive for a few weeks anyway.
My count was 55 at the start of the op - but they had to transfuse the 2 units of platelets they'd got ready as it was clear I wasn't clotting properly from the outset - count was 109 immediately afterwards, then 173 the day after, then 285 and 252 on Saturday. Since I had absolutely no emotional attachment to my spleen by the time the decision was made to go ahead with the op on Wednesday morning, I can safely say that I don't miss it one little bit!
So, the transfusions of 2 units of blood - needed because my haemoglobin levels were a bit low - in the 70's - and I had a few dizzy spells and palpitations in the hospital (which have been happening for a few weeks now in fact) and one major faint on Friday (a vesovagal syncope, I think it's called - heartbeat dropped to 28, blood pressure to 63/40 etc) that happened an hour before I was due to be discharged - my parents and Neil glad it happened in the hospital rather than at home! A bit of research this morning, and there are a few articles that link high doses of IVIG to anaemia, particularly if you are blood group A or B (I am group A) as IVIg can contain anti-A and anti-B antibodies, so of course you then destroy your own red blood cells and end up anaemic, giving all the symptoms I've been having for a few weeks. Anyone else heard of this or had similar reactions to IVIg? I've had weekly or twice weekly IVIg since the start of Jan, at 60mg or 70mg per dose, often on consecutive days - so if the research is right, that would explain a few things, which is a relief! Will talk to docs at the haematology clinic tomorrow about it to see what they think, anyway. Am on iron supplements anyway for a while, to take with my (now) daily antibiotics, so not a hardship!
