Suggest Treatment For Heavy Arms And Shaky Hands

I am 64 female, and fit, playing golf 3 times a week on a hilly course. I'm 5'10" and weigh 10st 6lb
Never smoked, drink 2 units alcohol 5 nights per week and only medication is HRT post hysterectomy 15 years ago. I take glucosamine and Calcium tablets as I have glucose intolerance.
I have been getting a heavy, dragging feeling down both arms tomy fingers and when I raise my hands (with a little difficulty) my hands shake very slightly. It passes off after a couple of minutes but is a bit disconcerting, especially when it once happened when out on the golf course.
Can you help?
