I was feeling my lower back on the left side. I was trying to rub pain out of my muscles and pulled up on my skin and muscles and noticed a semi large lump moving with my hand . Slight pain in the area, other worse pain around in the back. And I have been sleeping more than I ever have in the past. I have had an ultrasound on my neck for enlarged thyroid but it came back ok. Thanks for the help.
Hi, Greetings. Any lump is not supposed to be ignored. I suggest you to have an expert examination and opinion at the earliest.  I hope I'm of help.  Chat Doctor. B.
