Hi @Nick84, 
Welcome to the forum. 
I’m sure you’ll be hearing some of our members with their own experiences with twitching in the legs, however, in the meantime you can check out what they have shared in the past on this topic here: Why do my calves twitch constantly?
We also have a lot of information on restless leg syndrome on our website which also includes tips that you may find helpful, please visit our website here: Restless legs syndrome | Parkinson's UK
Lastly, we have a confidential and free helpline with a team of advisers who have a great deal of knowledge on this topic so feel free to give us a call when you can on 0808 800 0303 or email us at [email protected].
Best wishes,
Reah
