Medical expenses for bone marrow tr

In 2015 I was diagnosed with Multiple Myeloma.  Several courses of treatments have kept me functioning due to the capable care I have received.  Last year I went to the Mayo Clinic to be assessed for a bone marrow transplant, however it was not a possibility due to my failing condition.

Since then I have regained much of my strength and am preparing to schedule the transplant process again.  Only one glitch.  Although I had saved enough for the expense of being there (food, lodging, transportation)from prior generous donations from family and community, I recently was hit with a major prerequisite. I must get dental clearance to the tune of $3500, without which I can’t schedule the actual transplant. Any help would be appreciated!
