The NHS has let me down time and time again and its awful. The only way to get anything done seems to be to scream and shout and make the biggest fuss. Get on to PALs. Once PALs get involved everyone tends to take a bit more care. You are an out and out emergency if you have neurological symptoms like that, so you cannot let this go. If you arent up to it, get someone to liaise on your behalf. I’m sure you have someone but if you dont I will happily step in and contact them for you, just drop me a PM. I’ve got everything crossed for you!
