85 year old Pope Uses Elevator to Board , 1st time he hasn't climbed steps
VALLETTA (Reuters) - Pope Francis had to use an elevator to board a plane taking him to Malta on Saturday, with Vatican spokesman Matteo Bruni saying it was to "avoid unnecessary strain".
It was the first time in the pope's 36 trips abroad that he did not walk up the plane steps on his own. The 85-year-old pope, who is making a two-day visit to Malta, suffers from sciatica, a nerve condition that causes pain in his legs.
While on the plane, the pope was in good spirits when greeting journalists onboard, but he was walking down the aisle of the aircraft with difficulty.
He also used an elevator to disembark the plane once it landed in Valletta, Malta's capital.

I find low stress yoga exercises help mine greatly. My daughter got me a gift certificate for a local yoga studio which targets specific muscle/skeletal problems. They have different classes for a host of problems, from pregnancy to senior citizens with sciatica and other problems.
Some of the exercises are no more strenuous than sitting in a chair and raising your legs straight out.
There's also a bunch of the exercises on YouTube that don't cost anything.
They work, that's all I know. 
Do you ever get rid of sciatica? I need to know....
it will come back, but as soon as I start doing the exercises every day again it disappears.
The key is to make the exercises part if a daily regimen.
Try finding some on YouTube. Absolutely free!
I hope they help you like they helped me!
