Hello,
You may have suffered a mild
concussion and if this is true then, your symptoms are consistent with a POSTCONCUSSIVE headache which typically last on the order of several weeks to several months.
However, they have been documented as lasting as long as several years after the incident.
The key is to be properly diagnosed, AVOID taking excessive amounts of analgesics which are OTC such as
Tylenol,
Excedrin,
Motrin, etc. and not let the continuous
headaches get beyond 1 month without being brought under some level of control.
I recommend seeking out a headache specialist since it would also behoove you to be examined neurologically for possible other SYMPTOMS of CONCUSSION which may or may not be apparent to you and a neurologist/headache specialist will be looking for those things automatically when you start telling the story as to how everything happened.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Dariush Saghafi, Neurologist
