Hi there. Thank you for your question. I will be helping you out with your queries
From your description it seems likely that you are having what is called as a lipoma.
This is an extremely common fatty tumor and is absolutely harmless.
If its not bothering you I would not do anything about it.
If its causing you pain or any other symptoms or discomfort I would have it removed.
Let me know if you have any further questions.
Do rate me for my services when you are done asking.

Is this normal to have on one side and especially if you have lost a little weight too?
