Often moving pain is a sign of minor circulatory issues.
Bodily tissues don't like to be deprived of oxygen and generally express pain to complain about it.
If you are taking a statin or other cholesterol lowering drug, muscle weakness and pain is a very common side effect greatly helped by a supplement called Co-enzyme Q10.
If not taking such medications, would you try some Ginkgo Biloba? Check with the Doctor first if taking blood thinners but it should aid blood supply and oxygen delivery to the tissues.
