Slowly but surely

The pain from my mid back muscles has improved so now I'm trying to walk for 10 minutes a day to see how it goes.  I went outside for my first walk in 6 weeks yesterday.  Even though I had the stimulator on, the muscles in my left leg cramped so bad that I had to walk very slow and stopped several times.  I went for a walk again today.  It was pretty much the same as yesterday except the leg cramps were much worse.  I'll see what happens tomorrow.......
