If you snore loudly, it sounds like you may need to get checked for Obstructive Sleep Apnea. It can make days miserable. Snoring is the primary symptom.

You could also try elevating your head and shoulders to see if there is a position where you breath better.

Vision problems?
 

So it's been three months after my injury.

I am undergoing vestibular therapy to treat my balance and vision. I am also treating my neck, and according to the physio, my neck is a lot better not compared to post injury's. My tremors come and go. They don't bother me as much.

My sleep is alright now. I do wake up in the middle of the nights but I can get back to sleep quite easily. I don't have stressful dreams. My headaches are also much better: only mild and unnoticeable nowadays. My cognitive ability also gets better: I can think and work properly. My memory is still a bit rubbish sometimes; but that I can handle.

I feel like the only problem left for me is my eyes. It appears to me that this is the most consistent symptom so far, which appeared after I hit my head and is going on 24/7. I have realised most of my 'off-feeling' and mental fatigue come from my vision.

I don't get bad headaches looking at the computer. But I do find it a bit difficult to follow words and texts on screens and paper. I also realised that i have visual snow/ noise/ floaters, which makes my vision really bad when the weather is overcast or at night/ low light condition. My vision also got worse after I tried biking again or when i was over-stimulated or when i was tired. On one or two occasions, it hurts when i move my left eye around. I also realise that when I look into busy patterns of even complex concrete ground, everything seems a bit 'off' and blurry and wavy.

I am not entirely sure if the vestibular therapy will help to resolve those vision problems. Should I just keep resting and wait it out for those particular visual problems or should i see a specialist?

I suggest you check with a behavioral optometrist. NORA has a referral database. Home
Behavioral optometrists are also referred to as neuro optometrists. Neuro ophthalmologists are a different specialty.

I had a 90 minute vision test with a behavioural optometrist today and those are the diagnosis:

_Myopia, astigmatism, anisometropia acuity good with each eye.
_Little indication of VOR difficulties but half time slight undershoot on sacade.
_Stereo (depth perception) reduced both distance and near but severe in distance.
_Changing fixation: fast and accurate with no head movement.
_Pursuits showed smooth with no head movement.
_May have magnocellular deficit present.
_Fusion Range Dysfunction.

Apparently, my depth perception is completely screwed: I couldn't figure out the shapes coming out at me at all on the papers when the optometrist tested me. He tried glassed but it did not help me one bit. He said it may be permanent or it will improve with time.

I am only going to have one vision therapy treatment for home exercise since he said it is not needed for a full-program. We are going to do brock tring, NF Hart Chart, ME, SS syndrome.
