I have stage 2 brain cancer. Had surgery to de-bulk the large tumor growing into my motor neuron strip - ear to ear crainitomy that required 3 plates and about 40 staples. I hit my head the other night so hard I got a concussion. Today after the swelling has gone down I can feel what im assuming to be pins pushing into my skin from the inside, my plates have moved and I can feel a new " dip" in my skull. I'm so worried
