Welcome to NeuroTalk. Sorry to hear of your recent head bang injury.
The floaters may be just normal. A common problem with floaters is that when they are first noticed, the person gets a bit obsessed watching them. This obsessive characteristic is a common symptom of Post Concussion Syndrome. The flashing lights are also not uncommon, especially at night or in the dark. I have then any time I sneeze in the dark. I occasionally will see them at random times.
If they have you anxious, it may be worthwhile to get a doctor to check you out. The risky floaters have a color (pink, brown or red) to them. If you see those colors, get to an ER. They are rare compared to common floaters that look more like threads or hazy spots. These are just floating garbage. I went through this same concern early in my Post Concussion. These are the instruction the ophthalmologist gave me.
Peripheral vision oddities are often a similar cause. Your brain will usually ignore the peripheral image, knowing that it is an aberration. There are lots of peripheral images that are just specks, maybe a eye lash or eye lid skin flake that just catches your brain's attention. Again, the brain's lack of ability to ignore the image and then getting obsessed with these peripheral images make them worse.
I struggle with wild eye brow hairs that catch my attention. I need to keep them trimmed and my eyes clean of skin flakes. Once I see a wild hair, I am stuck until I either trim it or yank it.
bobbicat, Feel free to introduce yourself and tell us about your struggles. There are lots of good people here.
My best to you.

58 years old, retired due to disability, married 33 years, father of three, grandfather of four, Suffered a serious concussion at 10 years old (1965) stopped most driving after last concussion at 46 years old (2001), Post Concussion Syndrome/Multiple Concussion/Impact Syndrome with PTSD, immediate and short term visual and auditory memory problems, slowed processing speed, visual and auditory processing difficulties, insomnia, absence seizures, OCD, 14 concussions since first concussion at 8 years old, Taking paroxetine for 14 years and gabapentin for 12 years. Added L-Tryptophan and successfully stopped all paroxetine after 3 months of tapering down. I currently take 500 mgs of L-Tryptophan when I wake up, 500 mgs after breakfast with my vitamin regimen and 500 mgs late in the evening.
As of Nov 15th, Due to high stress issues resulting in PTSD, my docs put me on three meds. Clonazepam (Klonopin, a dreaded benzo but only for 30 days ) .125 mgs twice daily (Doc prescribed .25 mgs twice daily but half a tablet is doing good) , citalopram (Celexa), an SSRI , and olanzapine (Zyprexa), an atypical anti-psychotic before bed. I have lost over 30 pounds since mid July. The olanzapine is supposed to help me gain some of it back but it has just stopped the weight loss. They took me off the gabapentin. I am feeling better than I have in years.
I am also taking L-Theanine to help with GABA regulation
