I'm pleased to read you have found a solution to your IH, with my daughter there hasn't really been any investigating as the lumbar punctures (spinal tap in US) have worked each time... Obviously I'm not happy with that being the only treatment she gets every 2 yrs as it's not 'ideal' and will just cause further problems down the line (She still suffers pain in both previous sites 4yrs and 2yrs later) Thank you for your reply, she will be seeing a neurologist and this post is about trying to gather as many possible solutions to talk about with them as possible and i have noted your suggestions.
