Today I got a massage and the lady who massages me told me that I shouldn't be alarmed but maybe I might want to see a doctor. She said that every time she has massaged me she felt a tightness on my left side down near where my kidneys are on the left of my spine. I didn't know what she meant and she tried to show me how it felt but I can't feel anything. I have no pain. She said she didn't know it was a problem but it was just odd and might be something to have a doctor look at. Has anyone ever had a problem that this could be a symptom of? It makes me kind of nervous that I might have kidney problems and not know it.
