A warm welcome to the forum.
I thought you’d be interested to know that we have a ‘Sleep’ section on the Parkinson’s website which explores all the sleep related issues that people with Parkinson’s may experience. There’s a lot of information and advice which you may find very useful and we also have a helpline service where you can speak to a Parkinson’s specialist regarding the heavy and burning sensations in your leg. You can reach them on 0808 800 0303.
Do let us know how you get on.
