I Had A Epigastric Hernia Repaired With One Layer Of

I had a epigastric hernia repaired with one layer of mesh on the outside wall. I also had a hernia repair with mesh under my naval. The surgery was almost two weeks ago. At first abdominal pain was unbearable the first couple days. I controlled pain with prescribed medication about the first 5 days. Then just stuck to ibuprofen. 11 days after surgery I have a hard (as a rock) lump where incision was made on upper hernia. My other three incisions are fine. I have no stitches on the outside. All the incisions were glued and healed up very nice. But the lump is becoming more sore and tender to the touch and when any pressure touches the area. I have a 4 Month old baby that needs tending to and I have to carry him on my side instead of in the front. I can't tell if the lump is getting larger. After surgery the whole area was swollen and hard and now one large hard knot. Could this be caused by scar tissue? My concern is that it is becoming so sore and tender after 11 days?
