I have been diagnosed with lipoma beside my umbilical which has been causing me a lot of discomfort. My doctor has adviced that the only way to get rid of it is through surgery even though i control the pain with pain killer eg panadol extra. He also said it is a day ward surgery which means i could be discharged in a couple of hours.I am just a bit apprehensive as i have never had a surgery before. Is this a major surgery and is ok to feel this way?
