I felt a bump on my lower back that doubled in size over a few weeks. I have bad back pain when I sit which until finding the lump I put down to bad posture. 
After coming here to check what others say. Worrying, worrying more I finally went to the docs. Due to covid I could only get a telephone appointment. The first thing the doc said to me is there is no lymph nodes in the area of the small of back. I struggled to find that information online. Sure it tells you you can feel them on the back of your neck when you type it into the google but couldn't find anything on back. So anyone with the same worry as me I hope this helps a little. After that the doctor just said to leave the lump alone and revisit it in a few months. 
I asked to be referred to a private doctor at the local hospital as I wanted someone to actually look at me. At the hospital again the first thing the doctor/surgeon said was there is no lymph nodes there. Then after inspection he told me I was just fat. A Lipoma. I am probably 1 stone over weight so I am no way fat. I hope this again shows that you don't need to be fat to get a lipoma. The reason I wanted to post this here is I googled loads before the doctors and had myself worried sick. We all know we shouldn't but we do. However I very rarely see people coming back on their previous comments once they've finally been told what their lump or symptom is. So just wanted to say that my lump was harmless but caused me so much anxiety. My back pain has also pretty much disappeared as I'm no longer thinking of it 24/7

Thanks for your post. It almost exactly describes my lump, I also low back pain when sitting just now! I think I'll moniter it for a few weeks and see what it does. (I also have a large lipoma on my shoulder so must be prone to them)

I will try some tumeric olive oil paste fingercrossed will help :-) let me know how its going on x

Hi JohnW85 did you get urs checked out and conformed is Lipoma ? 

Hi do you have these lumps is yours hard 

Where Is your lump located ? So urs changes with the way it feels etc then? Mine feels hard/rubbery and moves about but seems worse when I bend over 

same by me its on lower back left side. i have feeling change sometimes its hard/ rubbery aswell . I have feeling sometimes it goes down a bit with swelling when check in mirror u clearly can see it and another days looks like gone but isnt its just not visible but when touch is theyre . when bend over its horrible sometimes painful or when sit too long same position. 

Is it like near your kidney area? I can't see mine can only feel it so worried though ,  has a doctor checked yours ? Did they seem worried if so? What kind of shape is yours and size roughly ?

Where was your lump located did it feel big 

hi sorry for late response my one is more like lower back left side on middle of trunk like where kidney's are located. When stand straight ist not much visible but soon bend over a bit then  you clearly can see it. I send my Gp picture as only online appoitments this times when found it and he wasnt worried about as never came back to me. Before send pictures he said if he thinks is something to worry about it he will get back to me and never went back to me at all so must be fine. My one is as said hard rubbery touch and only when u push on it its hurt sometimes. I m reckon is fatlump as seen alot in same position as my and theyre said its called Back Mice. I m a skinny person so its more visible by my i reckon. Size is like a Marble i would say maybe bit bigger .
