Meningitis can give rise to headache at any time. But, usually, if meningitis has recovered completely and it was not complicated, then it is unlikely.

But, meningitis can be associated with other neurological ailments which can give rise to headache not getting relieved with medication

Therefore, you need to consult a neurologist, do neuroimaging tests as advised by neurologist. Then the diagnosis and management would be appropriate

Thanks for your query. Headache usually subsides after settlement of meningitis. For more proper suggestion I would request you to give me the following information
1.     Duration of pain
2.     Exact side of the pain
3.     Is pain radiating from any other side?
Meanwhile you get done the following things
1.     B.P (hypotension or hypertension)
2.     Eyesight (error in near and far vision can cause headache)
Meanwhile you can take some mild tranquilizers omeprazole 0.5mg at bed time
Keep yourself busy and avoid excessive work on computer
If you don’t get relief,plz let me know onpakheim@gmail.com pakheim@yahoo.com
Hoping that you will get benefit from my advice.
My prayers are with you.
Thanks and best regards.
