Blue...I was dx'd with myofascial pain syndrome also...like Marlee. My lumps are like grisley, spongy knots and are in the muscle. I'm no doctor but cancerous lumps are usually hard and do not move under the skin, or so I was told when I was concerned about them. I get a massage when I can stand to be touched to have them worked out.
I stay as far away from Google as I can get! Don't go there...the worst case scenario always pops up first!
I get muscle knots and a gentle massage helps. I also have a fatty tumor on my back. It is mushy and sometimes it itches. Just get it checked out and try not to worry. It could be really nothing.
