[|AI|]  Hi thanks for your question had a bruise black eye and lump post motorcycle accident 4 months back. Your MRI and X-Ray skull at that time were normal (I presume so as you have not mentioned the report). Now you have developed swelling at same site which is red, and it hurts. The lump which you developed at time of accident was most probably a hematoma (collection of blood under skin and muscle). Most probably this hematoma didn't got resolved completely in 4 months (ideally should have got completely resolved in 4 months time) and now you have got super added infection of this hematoma causing pain and redness. I would suggest you to consult a general surgeon who may examine you and may prescribe you antibiotic and may Chat Doctor. Hope this answers your question.
