A cut from a grinder is a deep wound, and slow healing after stitch removal can happen if the area is still inflamed, infected, or repeatedly irritated. Cleaning it with hydrogen peroxide is not recommended for regular use because it can damage healthy healing tissue and delay wound repair, even though it may feel like it is keeping it clean. For better healing, the wound should usually be kept clean with normal saline or clean water and gently dried, without frequent harsh antiseptics. A simple non-stick dressing and keeping the area protected from dirt and friction are important. Some doctors may suggest topical antibiotic ointments or healing gels depending on how the wound looks, but the exact choice should be based on examination of the site, especially since grinder injuries can sometimes have deeper tissue damage or retained debris. It is also important to watch for signs of infection, such as increasing redness, pain, swelling, pus, or foul smell. If any of these are present, or if healing is not progressing, a surgical or wound care review is needed soon to prevent complications.
