I have Idiopathic thrombocytopenic purpura (ITP). During the past 20 years I've had it 3x's. Once in the early 90's after a severe sunburn and swimming in a local lake (metals from boats in lake water). Second time was two years ago when I was accidently poked in the leg with a tomato cage at the local hardware store. This second incident caused me to make the metal connection to the ITP. Recently I had a bone fusion in which a plate and 4 screws were used. I now have petechiae which has always accompanied the ITP. I am wondering if I need to have the plates and screws removed. This is very unnerving, would appreciate any input. My PCP said in passing that I might be allergic to the plate/screws and then a light bulb went off with the 2 prior incidents. My mom always told me 'you are the best advocate for your health' and I have always ascribed to this thinking...now I am seriously wondering if I am right and may need surgery again.
