I can understand your concern. You have multiple lumps.  It can be multiple lipomatous, neurofibromatosis or some other mass.  You should go for fine needle aspiration cytology or biopsy of one lump. It will give you exact diagnosis. Then you should take treatment according to diagnosis. 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. </s>
