Hello. Thank you for writing to us at healthcaremagic The bumps that you notice at the site of healing are most likely excessive scar tissue i.e hypertrophic or keloid scar. These usually develop as a result of an excessive tissue reparative response leading on to a raised scar. Keloids are usually itchy. Keloids may extend beyond the margin of the initial wound with finger like projections. I would suggest you to visit a dermatologist for a confirmatory diagnosis. Treatment of keloidal Or hypertrophic scaring is with silicone gel sheet pressure dressing. Intralesional injections of triamcinolone acetonide is also a treatment option; helps degrade excessive collagen tissue of raised scar and flattens them. Regards
