I had a laparotomy 2.5 weeks ago, everything looks fine on the outside but when i touch the scar, inside feels thicker on the left shud i be worried?

Laparotomy scar: Scars after surgerical procedures mature over about 6 months before the scarring process is complete. The majority of the collagen deposition and remodelling occurs during the first month. By about 2.5 weeks, the scar strength is about 65%, so it is not uncommon to feel hardness under the incision. Also, the surgeon may have left dissovable sutures under the skin which could also feel hard.

Not to worry: You may develop scar tissue and swellling, and the area may feel thicker as you mentioned. It will take some more days / weeks for the inflammation to completely go down. If you develop drainage through the scar or worsening pain you should contact your surgeon.
