<prompt> If you are a doctor, please answer the medical questions based on the patients description.i have lumps on both sides of my neck and it hurts when touched. Ive been lifting heavy things a week ago. I am also a cancer survivor with my last chemo last March 2013. I want to know if it has something to do with cancer or just overused muscles and nerves. Thanks for your response.  <response>: Hi. Great that you are a cancer survivor. If the lumps are fixed and move with muscle movements only, they can be from the over-used muscles, a sort of knot formation. Another possibility can be multiple lymph nodes as they are bilateral there is more chance of being infective in origin as they are painful too. Can be recurrence of cancer. The best way is to get a clinical examination by the Doctor and FNAC of the masses... Get a diagnosis and get stress-free.
