Lumps/Mes in upper abdominal area. What are they?

I thought a lipoma when I felt the first one, but now there are more. When I research cancer they talk about "the" tumor, not a legion of them! It is not isolated to one area. These can be felt on both the left and right sides of my upper stomach area. Am I feeling an organ or is that muscle tissue just underneath the skin? They're deep enough they don't show on the outside, but are easily found and felt with little effort or pressure. Don't say "see a doctor" as I have no insurance and no financial ability to do so. Do you know what these are?
