baseball,

Yes, a punch in the nose can be enough to cause a concussion. Your brain is much weaker now. Very minor impacts can have a devastating effect. There is no imaging that will help at this late date.

I learned recently that a CT or MRI taken at three days post injury is most likely to show any damage that exists. The Doctor/med school lecturer at Howard Hughes Medical Institute said that any damage will be evident by the third day but will be absorbed within a short period of time thereafter.

The damaged cells take a few days to die. It is only when they are dead that they will show up on an image. Within a few more days, the body will have absorbed the damaged tissue and neighboring healthy tissue will move in to fill the space. Once this happens, the image will be normal.

A qEEG could give some indication but it will depend on the interpretation. Probably not worth the money at this time.

Caffeine is definitely counter-indicated ( a no-no). Basically, caffeine messes with your adrenal system. It will speed up the timing of brain cell processing and this will cause the brain cells to overload and malfunction. It will delay healing.

I tried using caffeine to help me with sleepiness. When I told my doctor, he read me the riot act.

So, rest, stay away from people throwing punches and stay away from alcohol. Also, no caffeine, no aspartame (Equal artificial sweetener), no MSG. They all mess up an injured brain the same way. They overstimulate weak cells to the point that the weak cells can die.

Get some decent nutrition. B vitamins, B-2, B-6, B-12 and folic acid, niacin, thiamine, and Omega 3 oils with DHA and EPA are a good start. The brain needs them to function properly. A damaged brain needs them to heal.
