Hi Gerald, sorry you're dealing with this.
The ITP symptoms are caused by a low platelet count in your blood. Platelets are one of the elements that the body uses to form clots, so having a low platelet count interferes with clotting - typically you get bruised more often, take longer to stop bleeding from a cut, etc.
If you've been diagnosed with that, your body is not recognizing some of your platelets as your own and is killing some of them, then excreting them. So you're producing the right amount, but your immune system then kills them off.
It is chronic, but treated only if warranted. In kids, it can be caused by viral infections, and they usually recover fully from it. In adults it can be chronic, and the I (idiopathic) is the medical term for "we don't know what caused this". So the source is unknown or at least not attributable to any one thing.
It's usually treated by short term steroid use. Not long term since the side effects of that are worse than the problem. Have they treated you with this?
The ossification is usually caused by not icing enough or too early massage or strenuous exercise. Or it just happens. Ideally, it is reabsorbed into the body. What have they told you about this?
Again, sorry you're dealing with this - I'm a bilat from about the same time frame and have not had issues with the incisions, thankfully.
