It's quite common for scar tissue, especially after surgery, to feel a bit grainy or have small lumps—these are usually fibrous nodules or adhesions forming as part of the healing process. At 6 months post-op, some firmness and irregular texture can still be normal as your body continues remodeling the tissue. That said, the fact that one side is painful and has distinct nodules while the other is smooth does suggest some differences in healing or possibly minor complications like localized inflammation, small areas of fibrosis, or even trapped nerves. Here are a few things to consider • Normal healing: Scar tissue often feels firm or lumpy for many months and can remain somewhat tender. • Pain: Persistent pain or increasing pain isn't typical and might warrant evaluation. • Nodules: Small nodules can be from excess collagen or scar contracture but could also be small cysts or granulomas. • Infection or inflammation: If you have redness, warmth, swelling, or worsening pain, that needs prompt attention. • Physical therapy or massage: Gentle scar massage can sometimes help soften the tissue and improve mobility. • Consult your surgeon or a specialist: Since it's painful and uneven, it’s a good idea to get a professional assessment to rule out complications like hypertrophic scarring, keloids, or other issues. If the pain is worsening or you notice any signs of infection, increased swelling, or changes in the scar, definitely seek medical advice sooner rather than later.
