I'm 18, I was 17 last year, and I can't drive yet because I didn't get my permit

I'm still weak in the arms, and more weak in my left arm then my right, and it has officially been 2 weeks later. I forgot to include at the time this slap to the back of the head, my dad was driving backwards very slowly and slapped the back of my head. After this smack, I suddenly experienced weakness in my arms and legs and felt dizzy when I moved my head. When I was working I heard a brief low quiet ring in my right ear, which went away in a second or two. After that am hour later, my head started to hurt a little on the left front side for around a minute and went away. As of recently, I have been keep waking up 3:30 in the morning and have been not able to go back to sleep for an hour and a half. During this time, I would experience extreme anxiety and a dreaded feel of doom. Also, a few days back at my work, my boss called me in the office to go over some things, and I tried to listen to him, but everything felt so foggy and my stomach started gurgling and I was sweating in the rear. I was wondering if all of this is more likely to still be due to stress or is it more likely a concussion.

I would also like to add in there that is it possible for these symptoms to come from whiplash? Also, I forgot to add that as of last night, I woke up at 3:00 and I couldn't feel my toe, it went away in a minute or two, but is this even related?

What you have described could well be acute anxiety attacks.

One good way of dealing with them is to use a deep breathing exercise.

For example, breathe in deeply, count to 10, breathe out deeply, breathe in deeply, count to 10, breathe out deeply, .....

Doing a deep breathing exercise for 10 minutes or so is often highly effective in dealing with an acute anxiety attack.

But the thing is, acute anxiety doesn't last longer then 2 weeks and is also associated with rapid heartbeats so fast that it feels like a heart attack.

Hello Cavencruiser
Other members have tried to offer you support and helpful info, but at this point it would really be best if you please consult your own healthcare professionals about the symptoms you are experiencing, and that are causing you this continuous level of concern.

I am still experiencing all the symptoms, plus more, like slightly blurred vision and muscle twitches. I don't know what's going on, the doctor said I'm fine, but it seems that my symptoms will just never go away

Also, thanks for all the support. I appreciate it, but I'd like to add In that my eyesight slight blurriness problem reduces if I close my eyes and think of nothing for 10 seconds, but then when I try to read something up close and then look at something far, it appears blurry again. Also my leg felt like it had a slight burning sensation in it yesterday and when I was walking and looking at my phone, I moved my head upwards to continue walking, but when I did, I felt like my foot sank through the ground for a brief moment. And I also have problems finding the right words to use in sentences now sometimes.

By and large, any abnormal skin sensation you are feeling, like burning, is largely the result of the peripheral nervous symptom, so I concussion wouldn't cause it.

Also, the blurry vision and trouble thinking are both problems I experienced, but in my case I think it was probably all anxiety causing the issues, and I think that that's probably true for you too.

Sorry to bring this thread up again, but I still have had no improvement. And my mood constantly swings from normal, to a complete worry wart. I also keep waking up at night and also not able to stay asleep. My knee also feels a timed tingling sensation every 30 seconds. The feeling comes for about 5 seconds, then goes away, but then comes back again 30 seconds later. I was also in a panic mode again today, because I went to go make my lunch, and suddenly I have fell into a total panic attack. This is because as I went to go make my lunch, my arms were more unresponsive and I became very dizzy, and all of the things I had to do completely overwhelmed me, which never happened before. Like I said, I never had panic attacks like this before the smack, only if I was about to throw up. And when I was done eating I went to go floss my teeth, and then again, I noticed as I went to go pick something out of my tooth, that my arms coordination was off, and was harder to control, after this I started to get worried again, so I took in deep breaths. But little did I know, that made it even worse! I got even dizzier then before and it seemed like this wasn't helping so I stopped. It then look at my eyes in the mirror, and noticed that my pupils were slightly dilated, and I went to go to turn on the light, and when I did, my eyes did not respond to the light. This was still during one of those panic things btw, if that even matters. Even if I'm not thinking of my head, the symptoms still appear if I get up out of bed, or look at my phone then far away, I would feel lightheaded, or out of it. My muscles also twitch occasionally on my left side of my body, and my eyes flicker left to right occasionally for a split second when I am trying to look at something or am trying to focus or read. I also noticed a lot more floaters when I go outside as well, and strangely I feel quite ok outside, but when I go in the dark, I become lightheaded again. My stomach also growls a lot more than usual, and my vision is slightly worse. I think that there is no hope for me. My brain could possibly be concussed, and I could be experiencing real symptoms. Besides, my dad did, slap the back of my head after all, and I have read that put brains have the consistency of jello, so more than likely my brain probably jiggled around a bit and hit the wall of my skull. That is probably why I smelled that iron smell for a brief second at the time. I also want to add In there that I ran home from work yesterday, and while stopping to calm down, the world felt fake, and my vision started darkening for a second or two. Thank you again for your time.
