my 10 yr old daughter had crushing headache so severe took her to ER. she has previous history of sinusitis . They put her on antibiotics just incase and scheduled mri. Mri came back fine, except for cyst in sphenoid cavity. I took the results to ENT doctor and he said that it should not be causing headaches and told me to go to neurologist . It s been 6 weeks and my daughter has been bedridden, headaches ( frontal lobe mostly) are 24hrs never stop totaly but vary in pain. I took the MRi to neurologist and he said her brain mri looks fine and spenoid cyst is nothing. He put her on prednisolone 10 mg 2days, then 5 mg 2 days, then 2.5 2 days, and said it should work miracles. Wrong again, her pain is constant and hasn t decreased at all. I don t know what else to do, please help.
