Concussion from 4-5 years back but I don't know if I have long-term PCS
For context, my concussion came from when I went and boxed my friend who was much more athletic, taller, stronger, and heavier than me back when I was 15. I got hit consecutively in the left side of my head 3 times before calling it quits. I then went to the doctor who said that I had a minor concussion and that I'd be fine with rest and recovery for about a month. Then about 3 months later, I went to box again and I got hit in the same spot another 2 times.
(Yes I'm stupid).
Ever since then, I've had this weird feeling that the right side of my body isn't as natural as it used to be. It strains way quicker, like I get the burning sensation of exercise just from using it for a slightly above air-level task. My right side and my left side are both functionally equal and my right side might be stronger but that should be expected since I'm right hand dominant.
Balancing on my right leg is a bit harder than on my left, my right hand gets colder faster and more severely oddly enough, and this is probably placebo but using it a lot creates this weird hollow feeling in the left side of my head where I got struck. This one time when I went to the gym, I did some incline bench and my right arm started shaking uncontrollably, like it look liked jelly whenever I tried lifting with it which didn't used to happen and shouldn't happen considering my right arm is way stronger than my left.
Side note: I also have this aching in the left side of my head when I think hard.
All in all, my right side is stiffer and odder than my left and it feels like I'm controlling a robotic extension of my body rather than my left side, which is night and day.
I have not gone to the doctor and told them about this except this one time I asked this doctor's assistant why my arm felt so stiff and odd and she just said "carpal tunel" and I said alright because I play video games daily for long periods of time with bad posture.
The reason I have not told them is because it honestly does not get in the way of my day to day activities that much, it just makes strenuous physical work painful and tiring to a decent extent. That and I also get bad sleep, have terrible posture, am unathletic, bad diet, etc etc. I'm very unhealthy and my friends and family kept telling me that its my habits catching up or that its all in my head. That combined with the fact it hasn't interfered that much with my life besides making it generally worse slightly, and I've been too lazy to get it checked out because I'm scared of where it might lead. I know I should go see a doctor about this and I will.
MY QUESTION TO YOU IS
Should I be scared that this is permanent? I really don't know what a doctor can do if my brain circuitry is scrambled from repeated hits to the head. Is there anything I can do to make it better? Will this ever get better? Does anyone have personal experience with this? Will this only get worse?
Any comments are appreciated!
