Hi Rowanne a big warm
to the group and I'm so sorry you're having such a rough time.
Having IIH is hard enough but to have the complication of Chiari Malformation on top of it must be quite a battle. It could be having another Neuro look at you that they may be considering decompression for the Chiari. We have another member Charlie, who also has IIH and Chiari Malformation, and she had decompression surgery for it, and also has an Omayer reservoir on her shunt. Since her surgeries she is now back to horse riding and living a full life with her husband and 3 children, so don't give up hope about having your life back to normal.
I totally understand about colleagues not understanding your condition, mine were the same until I gave them information about it and told them it could happen to them without them even knowing it. I think because it's a neurological illness, and a rare one, as they will not have heard of it before they don't recognise it as a disease like they would cancer or multiple sclerosis for instance.
We have created guidesheets to help you explain to friends and colleagues about IIH here are the links you need that will help. I hope they help you, and we are here for advice and support anytime!
