Toe curling

Hi Janny,
Just found your advice about toe curling. Three toes on my pd side started curling intermittently a while ago. For a time I was able to push them straight, use foot wear with firm soles and “get on with life”. I mentioned it to PD nurse who referred me for physio - currently on waiting list.
But lately toes are curling tighter,more regularly and for longer. Resulting in hardened skin and corns. I’ve been concentrating on my legs and keeping walking. Never gave my poor feet a thought till now - silly me!
Sometimes I try walking on my heel to avoid my toes touching the floor - it doesn’t work of course.
I’m desperate to be able to keep walking with my dog - it’s my exercise.
Could you tell me if you still have botox injections and is it available on nhs?
I was diagnosed 2016 and am on sinemet. Thanks Daffy
