I've definitely suffered from my fair share of leg cramps. Usually, they strike after I've been standing for a long time in high heels, which is one of the reasons I try to wear heels as infrequently as possible.

The worst leg cramp I have ever experienced was in the middle of the night following a funeral where I'd stood in heels for nearly an entire day. I was fast asleep and the next thing I knew, I was gripped with pain so intense that it rivaled the pain I felt when I was in labor with my son. The pain was so awful that all I could do was massage my calf and scream. I knew that I needed to see a doctor to find out why I kept keeping such awful cramps in my legs.

After a visit with my doctor, I vowed to get up and move around as much as possible. You see, not only was I not getting enough potassium (I've fixed that), but I wasn’t walking around enough. At my job, I sit for five hours a day, six days a week and sometimes I get so absorbed in my work that I forget to get up and walk around and my doctor explained that not stretching and walking enough can lead to something much more serious than leg cramps.

According to research from the Pennington Biomedical Research Center in Baton Rouge, medical professionals have discovered is that sitting for as little as four hours a day can increase a person's risk of developing diabetes and heart disease, something doctors have now labeled "sitting disease."

If you're a runner and think that hitting the pavement is enough to reverse the damage done by sitting all day at work, think again. Medical professionals say that the only thing that will work is standing up from time to time.

Definitely memory bank this the next time you're sitting at your desk - it could end up saving your life!
