I have idiopathic intracranial hypertension. recently i have been falling down a lot of an average a month. should i be worried?

Maybe. See your doct: See your doctor or a neurologist or neurosurgeon. Increased intracranial pressure can cause symptoms with poor balance, walking problems, ataxia, etc and you should be evaluated professionally soon.

Yes: Falling down may indicate worsening intracranial pressure or worsening peripheral vision. See you ophthalmologist to check out your vision.
