Hi K.:
Mammograms are uncomfortable but they are over pretty quick so the discomfort doesn't last too long. I have had many because I also was diagnosed with a lump on my first mammo. I had it biopied and it turned out to be nothing. If I recall correctly I was told that most lumps (around 80%) are non cancerous. I think Motrin is a good idea and just try to relax. Best wishes to you.
