I do not have the exact symptoms as the original poster, but I seem to have some sort of systemic inflammation in my body and I accidentally found something that seem to work for me for my various inflammation-related pains. I am conveying this in case it helps others.
Background: My hands and fingers are particularly affected ( hands get puffy, the ball-like bones at the base of fingers get swollen evertime I sleep or take a nap, have difficulty clasping hands in the morning, have occasional swelling of various finger joints, have recurrent ganglion cysts, etc.). I have seen a rheumatlogist and all the blood tests came out normal. However, apparently, I have the HLA B-27 gene, which makes one prone to things like ankylosing spondilylits, psoriatic arthritis, and other arthritic tendencies. I tried Ibuprofen first and then Mobic. I had to quit Mobic when I gained several pounds in one week. I tried many supplements (Glucosamine, Chondroitin, Fish oil, Flax Oil, Vitamin D, MSM, Ginger, Bromelein, etc.) w/o much appreciable success. Then, almost accidentally, I found one thing that seems to work for me, although the effect only lasts for about four hours or so.
What Worked For Me: On an empty stomach, right after you wake up, just drink 1/2 cup to 1 cup of RAW (emphasis on RAW) green cabbage juice. This would be about what you would get from half a head of a medium-sized cabbage. I use cheese-cloth to filter the juice before drinking. (If you drink right after making it, it is not so bad). Almost miraculously, within half-an hour I can visibly feel my puffy hands and fingers become normal and the motions of the fingers and wrists become smooth. The effect seems to wear off after about four hours or so.
The problem: It is a lot of work to make and drink raw cabbage juice every four hours.
DISCLAIMER: This is NOT a substitute for medical advice. I am just describing my own (perhaps, unique) results. When it comes to inflammation-related health issues, individuals seem to differ widely in their response to various agents. What I describe seems to work for me. It may not work for you. I advise caution on any "internet remedies," including this in case you want to give it a try.
