I hit skull 6 months ago on the upper, right side (front) and it is still very sore to the touch. Any Ideas?

I was putting up groceries in my older fridge with upper and lower doors. I forgot the freezer door was open and hit my skull on upper right side, about 3" off center, when I arose from the Veggie Bin. It is still very sore to the touch after 6 months. I just probed and it almost brought me to my knees. However, I don't seem to have any other symptoms that are unusual. Vision is getting a little worse but, shoot, I am 68 years old and finally had to get gles two months ago. Just hurts to the touch. Any ideas of the cause? Particularly after this long? Any help would be appreciated. Thanks, Femalady
