Anybody with any advice or knowledge on this would be appreciated
Put quickly I hit the back of my head playing soccer. I was dizzy but didnt lose conscious or any memory any time later. 6 months later i still have a bump on the back of my head and the top of my head is swollen a bit, tender to the touch which gets me dizzy and a headache if i rub or touch.

Had a ct scan on the day of injury came out clear. 5 months later neurologist sent me to get an mri on my head. Hasnt called me anytime before my appointment so I would assume he found nothing. The radiologist showed me results my brain looked fine. Ran contrast on me and there were no leaks.

My question to ya is what are these bumps on my head? Are they skin tissue? If my brain and skull are fine according to those tests how come these bumps are giving me headaches and trouble talking at times? Any help would be greatly appreciated, (PS my neck make little weird noices when i turn left to right fully) but neuro said to worry about head first
