My goodness, and I thought I was suffering.
Even Reiter's at its onset in my youth was nothing like the sciatica can be now.
So on a hopefully constructive note, here is a list of remedies (gout not included):
1. Osteo-Biflex (highly recommended by Nimblewill)
2. Nabumetone (Relafen)in moderation – Much easier on the stomach than other NSAIDS, but probably equally dangerous to the kidneys if taken daily for long periods.
3. Nature's Bounty SAM-E. This one may be more dangerous, especially the other brands, and was denounced by a Russian pharma biologist I met staying in Twin Lakes, CO. But taken occasionally for a week to ten days actually works on the knees. Stop if liver enzymes elevate.
4. CVS Reparagen. This one is totally unproven, but has shown some signs of effectiveness in preserving knee cartilage.
5. Cobroxin. Available on-line. Supposedly highly diluted Cobra venom. The ultimate and possibly most dangerous remedy. But as John McCaine says, when the pain gets awful enough, you'll do anything to make it stop. Works for me when the sciatica gets really awful, and it will be weeks before I can get a steroid shot in the back.
6. Excercises prescribed by a PT. The flexing and stretching ones seem to help more than the muscle-building ones. Rowing machines are good, because the weight is off the lower body joints. After 8 years, I stopped my daily half-hour regimen four months ago and greatly increased the hiking, while maintaining the daily two-mile walk up and down a 600' vertical hill with the dogs. The jury's still out. The Merck Manual, of all things, has some excellent ones for various maladies, including sciatica and OA. I've experimented with many and have constantly revised the routine to see what seems most effective.
7. Booze reduced to between zero and none. No opiates other than for surgery/tests. Smoking anything is out of the question. Would drink MJ tea occasionally were it legal.
8. As close to a zero fat diet as possible, with emphasis on veggies, fish and poultry, in that order. Zero burgers, steaks and the like.
9. A pack suspension that gets very close to all the weight off the back and onto the pelvic crest. No lumbar pads or other pressure on the lower spine.
10. Exertion only in moderation. Life is short. Enjoy what's left.
This is all mostly trial and error, of course; but I know it has helped immeasurably.
Note the warnings – I disclaim all responsibility for anything.
