It started since more than 10 years back, I haven't do MRI, previously went Clinic only they are not helpful some say migraine some say sinus then give panadol which is not helping at all, after some research online recently find it more likely cluster headache.

Tried Coffee, dark chocollate, banana all sort of stuff, recent finding from ChatGPT suggest use ice pack on temple & back of neck which does help relief the pain a little.

Will visit neurologist see, just got a reference letter from clinic, most likely they might suggest MRI I guess.
