COPD, Maintenance
"I have been using spiriva for about 2 months.  I find my breathing has greatly improved.  I&#039;m not using my albuterol several times a day anymore, maybe a couple of times a week.  The only thing I have noticed is that I am getting severe muscle cramps in the front of my lower legs.  This happens mostly at night when I go to bed.  Has anyone else noticed this problem?"
