Good morning, @cweible19782006 Let’s get you Connected with some fellow members who also have Essential Thrombocythemia. ET is usually a very slowly developing condition where the bone marrow can start overproducing platelets. It’s in a category of blood cancers called Myeloproliferative Neoplasms where any of the blood components can be affected. I’m sure you’ve been pouring over information to find out as much as you can about your diagnosis.
Here are a few more informational articles for you:

Myeloproliferative Neoplasm from MDAnderson.org

We have several conversations in the group with fellow members, @eileen11108 @1995victoria @rjgregory440 @chetalbin @annetterzam and many others in this discussion on jak2 mutations. That genetic mutation can contribute to ET developing. You may or may not have that but the treatments can be similar.

~Essential Thrombocythemia: Looking for information and support

These are just a few to get you started. You can always type in key words such as ET, Essential Thrombocythemia, MPN (myeloproliferative neoplasms) in the search bar and it will bring up several more discussions.

If you haven’t already, I’d urge you to see a hematologist oncologist who specializes in blood cancers. This is treatable but it needs the correct diagnosis. Have you had any genetic testing done to see if you have the JAK2 mutation?
