So in addition to my other health conditions we now have another one to add to the list Idiopathic intracranial hypertension.
In idiopathic intracranial hypertension (IIH) there is raised pressure within the skull (raised intracranial pressure), which puts pressure on the brain. Idiopathic means that the cause of this raised pressure is unknown. The main symptoms are headache and loss of sight (visual loss). Treatment is aimed at preventing permanent visual loss and includes treatment with medicines. Brain surgery (neurosurgery) may also be used. For many people, a combination of medical and surgical treatment can help to control their symptoms well.
What a nightmare!! So they've started me on medication and drained off some of the excess fluid and it's wait and see now what happens next and if the pressure goes back up.
