@harleewine First, let me thank you for your service in our armed forces. I’m so sorry to hear that you’re experiencing low blood counts, most likely in relation to this chemical.

Unfortunately Agent Orange was collateral damage for many of our soldiers. My bother served just a little earlier than your tour in 1960-61. He and his troop were doused with AO while on a training exercise. Many developed blood cancers, including my brother, who passed away only 4 years later from Hodgkin’s lymphoma at the age of 27.
Back then, the army denied any correlation between AO and cancer. But too many people have come forward over the years and it is now obvious that it is the culprit.
The side effects of this chemical have been studied over the years and there are clear links to the damage it can cause. Including but not limited to blood cancers, neurological diseases, heart related issues, birth defects and the list goes on.

The VA has a publication regarding the potential disorders brought on by exposure.

I typed Agent Orange into a search of our Connect site. Here are the results. As you can see, there numerous other members who were also exposed and having issues.
So please look through these to see if there are any that are relevant for you.

Pancytopenia is a blood condition where not just one, but all your blood numbers are low. What type of treatment are you receiving for this? Is the VA helping with your treatment costs?
