Thanks Dynamo for sharing, you definitely have gone through rough stuff! Some 12 years ago, I was playing hockey in Finland and my team was playing against a bitter rival. They had an insane defenseman with whom I had a lot of quarrels during every game we had played against. In that game we exchanged words couple of times and I am quite good using words to disturb other players and enjoy doing it. Anyway, the game was tight and we were in the attacking zone. I didn't have a puck and I was looking for a scoring place around the net. I found a good scoring place and a free passing lane for the puck carrier, I saw him glance at me and then boom! Someone hit me and I lost my consciousness immediately. We had a male nurse playing in the team and he woke me up (still don't remember any of it). They ordered an ambulance and because the game was in the middle of nowhere, it took about 20 mins from the ambulance to get there and about an hour to go to hospital. When I "woke up" and I mean I started to realize my surroundings, the ambulance was 10 mins from the hospital. I was wondering what the h... has happened, I thought I was living yesterday and didn't have any recollection of the day at all. I was wondering, "hmm I have hockey equipment on and I am laying in the ambulance, but the game was supposed to be tomorrow. Now, there are couple of pieces missing in this puzzle", I started talking to the ambulance nurse and he told me what had happened. I was taken to the hospital, but they only x-rayed my head and neck to find fractures. After that they send me home. I was feeling really different, had bad headaches and nothing could ease them. Then my dad was having a 60- year birthday party a month later and the nurse from our team (he was working in a neurologist "department") came there as well. He asked me how I had been feeling and when I told, he "ordered" me to come to hospital the first thing next morning. I went to the hospital the next morning and they took me to the neurologist "department" right away. I spent there couple of days in different kinds of brain tests. Diagnose was that I had a severe concussion. The next 3 months (so total of 4 months) I had continuing headaches and nothing helped to ease them. Then they started to fade away slowly. First the headaches started to be more mild, then I had some days without any headaches, then I only had them after doing something physically demanding and then after a year I didn't have any effects of the incident anymore. But it took me one whole year not to feel any effect of it and I know it was my first, and only (so far), concussion. But still after 12 years I have problems with my neck, because of the hit. My friends have told me the insane defenseman had gathered a lot of speed and hit me even though I didn't have a puck and while I was watching the other direction. I suppose I got him all riled up with words and he decided to make me pay. He got sent out of the game. After the incident I ended my "career" in hockey. I continued playing hockey, but in much lower level leagues. So if one concussion can be that bad, then I don't even want to imagine how bad it feels after several concussions. I have been lucky to have only one concussion as my personality came back to normal after a year from the hit, but I can imagine after several concussions it might change permanently and I think that is definitely the worst part of everything relating in concussions.
