I am having dizziness, headache ( top and front more like dull tightness rather than migraine or throbbing headaches) which is making my eyes strainful and I feel like closing my eyes and sleep. Though I don't feel double vision or blurry vision but I do feel strain in my eyes. I have had 2 Brain MRIs. One in October 2023 and one in April 2024. They were clean and also had my blood tests CBC, LDH,
CRP, ESR and IL-6 all well with in the range. I generally take naproxen but it is not effective here. Am I looking at Glioblastoma. Can it develop in matter of 8-9 months?
