night help: I wake up every morning with a headache, burning eyes, an erection with a full bladder (even if I peed the night before) and gas. - Help.com

Your headache,burning eyes could be due to tension.
Are you eating the right foods?

Do you drink beer? Get used to the waking up with an erection. I am 52 and it still happens, just not every morning anymore.

Headache and burning eyes could be cause by an allergy, probably pollen allergy.
Drink less liquids (not more than 2 liters a day) and stop drinking two hours before going to sleep.

The erection is because of the bladder, it is an automatic response by the body when the bladder is overly-full, as it is impossible to urinate while erect. Burning eyes and headache are likely symptoms of dehydration. These are signs of kidney disease; the kidneys are not working properly and are pulling all of your fluids into your bladder. This could also be the prostate, but it is more likely the kidneys. Go to the doctor and pee in a cup, asap.

I doubt, that this applies as early as to a 15 y.o.

Yeah, probably not prostate, but it still sounds like early renal failure.

Neither.
A renal failure would show some more, different and very serious symptoms.
I’m quite sure that’s an “overload” of the bladder by consuming too much liquids.

Either way,if your so worried about it I would get it sorted.
If in doubt,get it checked out.
