Hello,
From the symptoms it can be a big cyst, lipoms or a fatty tumor or some benign growth. I suggest you to get it examined from a dermatologist and get a FNAC of this lump done to confirm the diagnosis. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
