Back and a little better

I went to the Doctor last Thursday and he did take me seriously.  Didn't know what was wrong but he understood that I was really hurting.  Along with 20 questions he took 5 viles of blood.  Three of the test came back negitive (white blood cell count for infection, liver problems and one other).  I guess 2 of the test were for inflamation which came back very high.  I guess this showed the inflamation in my joints?  Monday he put me on a round of predisone.  Along with the IB's I am getting some relief.  At least I can sleep thru the night (with the aide of sleeping pills).  So I am at least getting some rest.  Still don't know what caused this.  I still have enough pain that I don't feel like working out.  Of course that would be rather stupid.  I think the pain has caused my blood pressure to go up to the point (170/100) he put me on blood pressure meds.  I have always controled my blood pressure with exercise.  Since that is out I will take the meds. until I can get back to exercising.  Even though the pain is more managable the problem is still there.  Over the years I have had many injuries, this is so strange, I can't ever find the answer on the internet.  I will keep you posted on the saga of the swelling joints
