Yes, I have a swelling ankle...comes and goes. Xrays revealed
spurs on it in several places. It tends to flare when I climb steps alot.

You need to start methylB12 ASAP... get 5mg and take once a day on an empty stomach. You don't really need injections, and they typically are not the active form anyway.

A swelling foot/ankle can also be related to impaired glucose tolerance....it can signal Charcot foot. This is injury to the structure of the foot, when you develop changed sensory ability, and you should get a baseline foot Xray to make sure there are no spurs or hairline fractures developing. The foot and ankle are very complex and you can have more than one issue going on with any pain you have in the foot, or swelling.

I find using Morton's Epsom lotion is very helpful in removing discomfort and swelling for my ankle. You can get it at WalMart in the pharmacy area, and it is only 5.95. Rub it on your ankle and the top of your foot once a day and see what happens.

If you choose you can also soak in lukewarm epsom salts in the tub, but the lotion is so much more convenient.

There are 3 major nutrients many Americans are low in because of poor diet and lifestyle.
1) magnesium (up to 70% are low)
2) Vit D (up to 70% are low)
3) B12 (up to 40% are low)

These are all easy to correct, and not expensive and deliver quite a bang for the bucks they cost.
