Just as well you found this forum as there is so much help and support on here as well as the main site and helpline.
I too am recently diagnosed and quickly discovered that you have to be proactive. I found the number for the PD Nurse in Leeds and rang them to make sure I was on their radar and got an appointment within a week. I had to keep chasing when I was waiting for medication and have done the same with physio.
From what I can gather being in this forum not all areas have a NHS Neuro Physio so you might be sent to a general physio which is nowhere near the same. In Leeds there is a Neuro physio but with a long waiting list so I asked puk to recommend a private one which I’ve signed up with. I was told that exercise is very important but adding in the PD specific exercises is even more so. I have been doing 3 different exercise for 3 weeks as well as forced walking and have noticed a big improvement in how I’m able to move my left side but more specifically my fingers work better.
Hope this helps and you get some support soon
