Hope you got CT scan or MRI done after the concussions as there are 3 types. It heals on its own within days, months or even a year. Do not get involved in any sport or wrestling that has risk of head injuries for some time. Maybe you can consult an ENT in case you have some dizziness or uneasiness.
If feeling depressed or anxiety a Psychologist can help you with therapy.
Next Steps
Consult the doctor who attended on you when you had concussion. He/She can guide you better.
