Hi Kathie,

I had been diagnosed with a very large thymoma in May 2009. My symptoms started 5/1/09 and by 5/12/09 I was in the ER. I did experience what I would call chest pressure when I would lay down. This started around 5/1 and I thought it was odd that I didn't feel the same pressure when I was upright.

When I went to the ER, they thought I had MS until they took a X-ray, then a CT scan which showed the thymoma.

I'm thankful that my symptoms didn't last for years before my diagnosis, but I'm in no way thankful with my life now.

Good luck,
Southern Bell
