Just turned 50 and waking up to sore knuckles

After just turning 50, I am noticing some changes.  First of all, back in my younger days I used to hit a heavy bag quite a lot and stopped, then restarted but haven't for over two years.  Lately, I have been waking up and my hands feel quite tight in the knuckle area.  I don't think the heavy bag was the issue since I did not punch the bag as much with my left hand, however both hands feel the same.  I have also had some pain in my feet.  Sharp pains mostly on the sole area beneath the toes.  My last blood test said my glucose was a tad high but my Doctor did not seem worried.  i have taken RX fish oil for over a year.  Thoughts?

I will be turning 48 at the end of this month. I just passed the year mark with out a period so I guess that is menopause now, along with this came a rise in blood pressure, hot flashes and now sorenesss in joints. Mostly in hands and thumbs hurt the most in the joints. I had blood test done and I tested positive for RA. Waiting to see a RA doctor, seems like long wait or there is alot of people getting it. I have done some internet reading and they say fish oil is good, helps keep joints lubricated. I also take tumric with bio-pepperin for anti-inflammatory. i am still finding other natural ways to treat it.

This is rather odd to me since nothing has ever hurt before.

Yeah, I have arthritis in the knees and feet and now have tightness in the fingers.  When does it stop???

Do hand exercises - make a tight fist and then splay fingers out about twenty times a day.  Movement is essential hopefully to keep it at bay.
