What do spinal mets feel like?

Anonymous

I ask because I have gotten 3 epidural anesthesia injections for back pain, and the pain has improved a lot.  Now, I have this "annoyance" in my spine.  I asked my doc about it and she said, "You are describing this a little differently than most, but many patients describe a feeling of pressure in their back after getting the shots.  It is basically indicative of healing taking place." 

The super-freak in me worries that this is a tumor on my spine, but it doesn't hurt a bit.  I just feel like there is something incredibly annoying there. 

Any thoughts?
