[|Human|] I have a marble like lump on the right side of my lower back that has been there for several months, it feels at times as if there are two of them. I went to the dr and he said that if they do not go away to seek another opinion. Could this be a muscle spasm or something more serious?
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You may have some soft tissue tumor like lipoma, neurofibroma or dermatofibroma on your back. Or you may have some other soft tissue tumor.  You should go for fine needle aspiration cytology or biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
