i just felt the back of my head. It was hurting, a few weeks ago i kept passing out. I went to e.r. they said they couldn t help me. Gave me medicine for vertigo. On the back of my head i feel a huge mass, baseball like. What is going on with me, its numb. But yet it hurts and I don t feel right lately. The e.r. doctor ran blood test and ex rest of my chest. They all came back I am very healthy. I am 28, female, 5 4 and I weigh 270. Please don t say it my weight. My blood pressure is normal, my blood sugar was low. I asked for a cat scan the denied me. My question is why is my head literally swollen. I m nervous, I don t know how long its been there. I just noticed something was not right today.
