I have been dealing with a low platelet cont for the past two years my doctor tells me that they don't know what the cause of my ITP is. Started out with infusions and moved to promacta when that didn't work I started receiving weekly injection shots. As of November 15 my platelet count was at 8000 and fluctuates every time I see my oncologist. This is very frustrating not knowing what in the world is going on with my body.
