<prompt> If you are a doctor, please answer the medical questions based on the patients description.I had a spinal fusion surgery about 3 weeks ago. I have been doing extremely well. However yesterday I just noticed to the right of the top of my incision feels like there is a lump under the skin. Not really physically noticeable but you can feel it when you touch it. It is not extremely painful just feels a little sore. Should I be worried?  <response>: Hi, Thank you for posting your query. First, I would like to reassure you that your symptoms do not suggest any serious problem. There could be small swelling at the site of incision, due to old bloodhealing tissues. If you develop fever or if the area becomes tender, you should get it checked by the Neurosurgeon to exclude a local infection. I hope it helps. Please get back if you require any additional information. Best wishes, Chat Doctor. Ly
