Hi! there is a great community of people on the Australian site of FND Hope, it really depends on where you are. The moderators have put together a list of professionals who specialise in the diagnosis and treatment of FND. However, that said I also have seen so many different doctors and trying to get in to see people is like pushing a boulder uphill. If you are international or in the U.S try to find a good physiotherapist (or occupational therapist) part of this condition is to find a way to "fix the pathway that got broken" (i.e to retrain yourself to walk). I don't know where you are but what I do know if that the US is even behind in terms of treatment care of patients.
There are three main areas of getting help
1. Old fashioned psychiatry (however with someone who knows that the DSM-5 has been updated, so before making an appointment check to find out if the practitioner knows this and also knows that there is an actual diagnosis test for FND)
2, General Doctor who is able to prescribe some kind of drug like diazapem ) again not all things work the same for everyone this drug allows me to function to be able to type this response etc etc
3. Physio who has knowledge and has worked with movement disorders
There is no quick fix and no one method. Everyone gets different symptoms, also sometimes like in my case the symptoms change. neurosymptoms.com also has info.
Most of the time, this disorder is terribly isolating. I lost my job, my life and so many other things due to this condition. I am now in financial ruin due to the medical costs. AND I STILL do not have a clean view of recovery. i.e I still need to find a physio to help me with movement disorders etc. This disorder is horribly isolating. So join FND Hope where ever you are.
