There IS a veteran's group: http://www.fencing.net/forums/groups/vet-fencers.html

There's a little header in the upper right, something like "Group Tools". Click that and there's a "Join" option.

My sister has arthritis she's got a lot of good advice and help from the "Arthritis Centre". In Canada hospitals/ charities will often create outpatient centres for people with common medical issues. Perhaps you have something similar locally?

Non-prescription treatments she has found to help her are Boswellia, MSM, & Omega 3 oils.

Most people know about fish/ flax oils/ Omega 3's.*
Here's a link to what the other two are:

I found MSM works better for my joints than glucosamine does, plus MSM is naturally found in foods where glucosamine isn't a normal part of one's diet so it's not considered either a mineral or vitamin supplement.

As with most vitamin/ herbal remedies it can take several weeks to notice a difference. The benefits over some pharmaceuticals is that they can be easier on your gut and overall health.

*I rely on Omega 3's to keep my many old knee injuries from affecting my mobility. Since pulling half the ligaments in my knees several times, I wasn't able to climb stairs or walk without pain... in my 20's & 30's. A lot of the advice my sister has gotten on joint pain has come from me & confirmed by the Arthritis Centre's findings. There's hardly a joint in my body that I haven't mangled while playing some contact sport.

Go ahead and start forum threads. If there are enough Vet related ones, then I would create that sub-forum. Without the content telling me there is enough interest for it's own sub-forum, there's not much justification for creating it.

I'd just as soon hang in with the general fencing forum myself--the young'uns put up with us just fine!
