I Feel Like I Have Started Repeating My Health History
Most probably not related to tumors.
Detailed Answer:
Hello dear welcome to Ask a doctor's service.
I read your query and here is my advice.
I don't find this headache to be much related to any brain tumors since you don't have other symptoms related to brain issues.
I think you may need to visit a dentist or an maxillofacial surgeon to check your Temporomandibular joint and your teeth alignment. Any issues with TMJ dysfunction may cause headache.
In most of the cases there isn't a specific reason for headache. You can also visit s neurologist for an EEG or other examinations about it. Anxiety can also contribute to it.
Ibuprofen can help but you also can use Diclofenac or ketoprofene .
Hope I have answered the question.
Let me know if I can assist you further.
