I've had on and off aCL and LA, but don't know of this third item mentioned...something I might wish to inquire about. I also have low platelets. Have had this for decades. It's been very serious twice. Recently, it's an issue again, but we are in wait and see mode.
On another site I go to sometimes,I was shocked when a young woman posted that her boyfriend with extremely low platelets was given IVIG and a medication to treat low platelets. A few days later, he had chest pain and was rushed to the hospital with blood clots in his lung.
Years ago, I was told it was unlikely I would ever need to worry about clotting.hmmm.
Anyway, several mentioned that if you have anti phospholipid antibody and are treated too aggressively for ITP this could happen!

WTH?!?! My hematologist, isn't even aware that I've had this dx and continue to receive it now and then by other docs.
I will need to tell her.
I have all sorts of autoimmune "stuff." Some years have been rough. I've only had nerve pain recently.
By the way, after our grandchild was born, I caught a lot of colds etc. while visiting and my hematologist felt this caused my recent troubles. I suspect viruses and /or infections can cause havoc for folks with autoimmune issues.
