I hit my head a week ago on a steel frame and it still hurts and I get dizzy easily. Whats wrong?

Need to tell your MD. Sometimes dizziness, drowsiness, headache, nausea, troublee with balance, mean increasing pressure on brain die to bleeding beneath the cover of the brain (dura).
PostConcussion. This can be serious. Until one month after the symptoms resolve, it is essential that you do not risk any second impact to your head. If this persists, a visit to a neurologist is in order. Read about post-concussion syndrome and second impact syndrome online. I'm sorry this happened -- good luck.
