It usually takes six months to a year for a hard post-surgical incision to clear up. The hard lumps are actually scar tissue formed during the healing process of the surgical incision and generally do not require special treatment. In the early stage of wound healing, there may be subcutaneous hard nodules, patients can use local hot compresses or infrared physical therapy, etc. to facilitate the absorption of hard nodules; after the wound has recovered for a period of time, there are raised hard nodules at the wound, you can also use local hot compresses to soften the scars, or perform appropriate massage to promote blood circulation and fade the scar growth. If the hard lump remains unchanged after six months, it can be solved by various ways such as scar cutting, laser, and surgical treatment to remove it. In conclusion, patients should not worry excessively in general and keep a calm mind so as not to be affected by the disease. Pay attention to light and nutritious diet, and eat less spicy and stimulating food.
