CSCSA South east Buckinghamshire

I live in South Bucks. Is there anyone that I can contact. I’m on my way to hospital as an emergency regarding the loss of use of my left leg. I cancelled Christmas with my son and live alone. I’m under the mental health system but because of the overload and it’s my PTSD that has got me there. During my time in Afghanistan as a medic I was injured in my back and have had 2 ops already. Not sure I should be going into hospital. Any thoughts?
