I have been on 90mg of Cymbalta and 150mg of Lyrica for about 9 months, and still experiencing pain each day with severe pain and flare ups a few times per week.

I recently had my vitamin D level measured. It was 40ng/ml. I started taking a 5000iu of vitamin D per day. I increased the dose by 1000 each day until reaching 15,000.

Within 10 days my pain had diminished by an astonishing amount, more than 50%. I still get an occasional flare up, maybe once every two weeks or so, but it is far less intense and goes away quickly, whereas in the past it would last all day, and not go away until I had slept.

Previously i was unable to stand on court and teach tennis for more than an hour without pain. i can now stand on court and teach for 6 hours!

Now my legs get tired before my feet start hurting. In fact my feet hardly ever start hurting from standing. The only thing that occasionally sets them off now is stress.

It is absolutely amazing. The vitamin D has had as much impact as the drugs, possibly even more, and the improvement seems to be ongoing.

I have been taking it for 5 weeks now, and will continue at this level for a while to see what happens before trying a higher dose, or maybe a reduction in the drugs.
