Do I have SEVERE HEAD INJURY and need surgery?

PLEASE READ:

It's April now. In November I had hit my head on a stone floor and fractured my arm too. The doctors didn't seem concerned about my head as the arm needed surgery.

I felt something on my scalp that could only be described as a cracked membrane. I couldn't open my jaw. So I had the doctors look at it and they said that it was a "SCALP CONTUSION" which they said was nothing and always goes away on it's own in good time...

It has healed about 80%. It was so painful but now it only makes me uncomfortable if I press the area. I have some very mild pain/discomfort that sometimes comes ON IT'S OWN after I smoke. I also found that that area is like a very tiny portion of my has come up. In the shape of a hill. LOL. It's probably only 1mm high though.

Everything is fine now, and I have felt mentally the SAME THROUGHOUT. I don't have any symptoms usually accompanied by a head injury, except that tiny bump I found and pain in that area after smoking. BUT ALL THE OTHER PAINS HAVE GONE.

Will this go away too? Has skull cracked? Do I REALLY need to go to a doctor? Cuz I don't want to and everything is fine like I said.
