Hello,
You had
concussion last summer and almost it has taken 1 year to just recover from your concussion symptoms. The duration and severity of symptoms depend upon the amount of concussion. The symptoms of a concussion may be physical damage to the brain and neuropsychiatric problems. I need not to say much about the symptoms, as you have experienced all those symptoms. The duration of this status is unpredictable.
Post concussion also the symptoms may persist like
headaches,
dizziness, fatigue,
anxiety, memory and attention problems, sleep problems, and irritability.
You are not advised to consume alcohol or drugs, as they may delay the healing process
Your behavior changes like irritability, slow reaction may be due to to the concussion only. But you must keep in your mind that all these changes are reversible with medicines and
meditation.
Even though alcohol has not affected your hormone, you have to avoid it.
Full erection is possible by avoiding frustration, tension, angry and irritation.
Wait patiently, you will recover to the pre concussion stage.
You need time and patience.
Wishing you a speedy recovery
