Hi Lesley
My son has only had ITP for a little over a year now and I am fortunate because he was 10 when he got diagnosed. I haven't got it sussed myself a lot of the time, but I was trying to decide what my advice would be, and I came up with the following
1. Panic is not helpful, and neither is worrying.
2. Preparation and advance planning are helpful - things like making sure you know what to do, the school know what to look out for and what to do if there is a problem
3. Try to keep life as normal as possible - don't let ITP take over your life or your sons. Its difficult to do, but put your preparations into place, and then just try to get on with life. My son does pretty much anything he used to do, but with some modifications - helmet on his bike, no heading the football.....
4. Treats for hospital visits seem to work well - we always play "guess the platelet count" beforehand, and then we treat ourselves to a fast food lunch on the way home for guessing near (even if it is 100s out!!). Don't make a big deal of blood tests though.
5. I agree with the previous answer that keeping a diary of symptoms, blood test results etc is helpful - if nothing else, it makes you feel more in control, and with ITP, its very easy to feel very OUT of control.
I don't have much experience of treatments, because in the UK, very few kids get treated for ITP - most just do wait and watch. But from what I read, IVIG is a short term treatment so getting bruising again would be expected. Maybe its time for another blood test?
Good luck with it all, Ali
