@devildeepbluesea, I was diagnosed with sciatica a few months ago. In my case, it's being caused by some arthritis in my lower back. Don't rely on ibuprofen on a regular basis. It will cause stomach ulcers if overused. Ask your doctor to let you try gabapentin, 100mg twice a day.
Gabapentin (Oral Route)
It's been a godsend for me, really helpful.
By the way, for all of the new posters, since I am not a typical Mumsneter, here's a bit about me. I'm an American who has never been to the UK, though my DH used to live there. I first heard about MN in a article in The Economist five or six years ago. I live a bit north of New York City in this area:
The Hudson Highlands
I'm an HCP, have two kids in uni (which is eye wateringly expensive here) and been happily married for 25 years. DH, who is a really good egg, has promised to show me London at some point, which I'm really looking forward to.
And speaking of DH, he's gone off to a work event for the day, so I have some very rare alone time in the house. I'll probably clean out the upright freezer in the garage then ring my boyfriend to see if he can come over.
Just kidding.
