Hi. Thanks for your query and an elucidate history. You have to undergo a proper clinical examination to be done by a Doctor who can catch many of the problems on your proper history and physical examination and can then guide for further investigations and treatment. I would suggest to undergo high resolution ultrasonography and FNAC=fine needle aspiration cytology. This will give the perfect diagnosis and aid the clinical diagnosis. Once the diagnosis is made the proper treatment, which in your case can be surgery only. Remember a simple principle : anything which is growing for no obvious reason has to removed and subjected to histopathology examination, even though these are lipomas
