Treatment functional neurology

I’m reaching out in the hope that someone might be able to help me get some medical investigations that I desperately need. I used to be a very active and independent person. Martial arts were a big part of my life, I was also a musician, and a nature photographer. I never imagined that one day even taking a shower would become something I barely can do do on my own because of the seizures and feinting and I also live alone. Several years ago, I suffered a neck injury in an accident, and since then my health has progressively affected almost every aspect of my life. I’m now trying to investigate possible problems with blood flow to my brain. Unfortunately, the specialised tests I need aren’t available through healthcare system. I’ve found a private functional neurology clinic in another city that can perform the investigations, but the cost is around €700, and I’ll also need to travel and stay there for 1–3 days. This illness made it almost impossible to save for something this expensive as I can no longer even keep a part time job. I don’t know how this works and I don’t expect anyone to cover the whole cost, but any contribution, however small, would genuinely help me get closer to finding answers even if it takes years. I just want a chance to find out what’s happening to me and hopefully get the treatment I need and reclaim some of the life I’ve lost. Thank you for taking the time to read this. ❤️
