I don’t think there are, well at least I haven’t found one yet (please let us all know if you find one!). You just have to find a consultant who could possibly diagnose the raised intra-cranial pressure based on one of the medical signs, such as a Neuro-opthalmologist who might find a swollen optic disc – though remember you can have raised ICP without this sign. I was lucky and this sign was visible (though it wasn’t blatant) but I was able to obtain Diamox. I only needed a small dose and it made such a difference.
