Hi, thanks for asking from HCM. I can understand your concern. After 2 years, your injury must be healed, unless there is some pus discharge or CSF discharge. It can occur if there was bone and dura damage, which did not heal. You can get it examined by doctor. If there will be active wound, he will try to rule out - chronic sinus due to osteomyelitis/ingrowing hair - CSF leak due to dural and bone damage If there is doubt, he might ask for NCCT head and/or MRI brain. Further treatment will depend upon diagnosis. Usually both scenarios need active surgical treatment. Excision of infected bone and antibiotic course. In case of CSF leak, repair of dura and bone defect will be needed. Another more likely possibility is healed hypertrophied scar. It can feel like swelling, appears red/pink and may be tender sometime. But it is a scar (means healed area). There is no need to do anything if no severe pain and it is covered in hair. The feeling of pounding is due to radiation of pain at this area. It is normal to have pain radiation at scar site. For pain, you can take tablet Acetaminophen or diclofenac after proper prescription. Hope it will help you. If still having doubts, do let me know. Thanks. Take care. Dr Ishu Bishnoi
