Do not worry bpadilla. I have seen many of your topics and know you have had a lot of the same fears I've had. Lymphoma was my worst and latest, ending a few weeks ago when I finally got an oncologist to order me an MRI of my chest and abdomen. That fear lasted 7 months and I knew I was done for. I'm not, thank The Lord. :)
When I was 19 I had an intense brain tumor fear with a stabbing sharp pain in my head that lasted two weeks. Pain meds didn't touch it. I went to a neurologist who did some basic office tests, I told her I thought it was a tumor, and she sent for off for an MRI. She didn't think I had a tumor but she could see how upset and nervous I was. I got my MRI then went back a few days later to go over the results. Nothing! No tumor. :) my head pain went away shortly after. Never knew what is was but it wasn't harmful.
I've been sent for many a test, usually because I'm so worked up and the doc wants to reasure me. Bad habit to get into....
Btw with my head MRI, I had to wait until the appt to go over results. With my last body MRI, the oncologist called me the next day telling me the good news. Either way, whether they call or you go to the office, doesn't determine what they tell you.
