Hi, newb here. I am really worried and not sure what to do or if there is even anything really wrong with me.

I was sitting at kitchen table Monday night (9/14) and was laughing and hit the back of my head on the countertop behind me which is pure, hard, real and thick marble. (rental condo)

Within two hours I went to ER and they did the old flashlight, squeeze my fingers and then gave me a CT and said it was okay

Two day later on Wednesday I woke up with my right eye really blurry and I was still very disoriented, weak, sensitive to light and couldn't concentrate. I went to another ER as I was now in a new city and so they did a follow up CT and also said I was fine but had probably a concussion.

It is now almost a week and my entire brain is ITCHING what the heck is that? I did not lose consciousness that I know of. I am also still very nauseated, can't think straight, confused, scared. Forgot to mention BLURRED VISION like big time.

Forgot to mention when I hit the back of my head it was more the left side and middle and after I hit and sat back straight up in the chair I had a sharp pain in the front left side of my forehead. I am totally freaking out that I had my brain slam and I am going to have my kids find me dead here one morning on vacation. I am so far from home and have a long drive and not sure if it is all just the fear or if the itching means a brain bleed not being picked up by CT. (I almost typed radar, that is how far gone I am right now)

Any help, advice, etc would be much appreciated. Thanks in advance.
