When I got off the plane in Boston for the Enterprise 2.0 Conference, two weeks ago, I was barely able to walk. The pain was almost unbearable - so much so that I even called my wife and mentioned that I might need her to fly to Boston to help me return to California. My roommate, Michael, got me some Motrin and ice packs and I rested for the night. By morning, I was feeling a little better, and I was able to make it through the conference with small recurrences during the week. I was even able to blog the conference with Michael.
The flight home was a only slightly easier; I made sure to get up and walk around during the flight. However, getting out of the car after my two-hour drive from LAX to David Allen's office in Ojai was again extremely painful as was the case on my return trip home.
Today, after church, I could again barely walk, so my wife took me to Urgent Care; we were concerned that this apparent hip problem was growing more serious. After a brief history and physical exam the doctor concluded that I was suffering from Piriformis Syndrome, more commonly known as Wallet Sciatica. The bottom line (pun intended) is that while I have an ample amount of "padding" in certain places, one place I'm lacking it is on the backside. This means that sitting for prolonged periods makes it easy to pinched the sciatic nerve -- the source of my great pain.
Thanks to my Grahl Duo-Back chair, I can comfortably sit at my think station for many hours at a time with no pain. But, when I'm at home, I don't carry a wallet and a certainly don't sit on one. Lately, however, I've been doing more travelling and sitting on my wallet. Therein lies (or, more accurately, sits) the problem. Sitting on my wallet in airplane seat for hours at a time was the cause of my Sciatica - Wallet Sciatica. My doctor advised me to use a thin wallet and to carry it in my front pocket. My super-cool David Allen NoteTaker Wallet is wonderfully thin when I keep my cash and business cards separately - which I did not do for the trip to Boston.
If you carry a fat wallet, think about thinning it out and carrying it in your front pocket or coat.
Tonight, I'm resting comfortably on pillows and taking anti-inflammatory meds to relieve the swelling around the pinched nerve. Hopefully, in a few weeks, I'll be as good as before.
I found this site helpful in understanding the problem. (They apparently also sell a super thin wallet of their own.)
