2 Months Ago I Got A Hard Hit On The

2 months ago I got a hard hit on the right side of my forehead, I didn't feel anything other than pain cause It was swollen with a purple-reddish colour, I used Reparil Gel for a week and the bruise was gone, but till now when I press on it even without giving force on it I feel pain on it only, can you please guide me what to do and tell me if it is a serious issue or not?
