I think from your description that I’ve had a similar problem, but fortunately learned to be able to overcome it.
Being aware of the issue gives you a good chance of overcoming it too, but I’d suggest its not something to ignore.
If you find it difficult to sort out by yourself ….such that you feel confident….. I suggest you ask your GP or Consultant to refer you to a neuro-physiotherapist.
What you’re describing sounds to me as though it may be ‘associated movement’ for example when you move your head your arms follow, rather than stay where they were.
