Should Lipomas on Shoulder and Back Be Removed?

In a year, I have developed two egg size lipomas. One in the small of my back and the other on top of my shoulder. The one in my back appeared out of nowhere. It has caused a lot of issues at times with walking.

I was doing push ups and felt a pop in my shoulder and it really hurt, then I noticed a lump on top of my shoulder, as if it popped up through the joint. My shoulder hurt for at least a week. Should I remove these? Or have reason to worry?
