Simple causes include trauma and external injuries (pulled muscles, strained ligaments, dislocated joints, bone fractures); complicated causes include infection, autoimmune disorders, crystal-induced inflammation, and non-inflammatory tissue degeneration. Optimal treatment must address the symptoms (pain and inflammation) and the underlying causes. After the disorder is stabilized, physical therapy and exercise are important to maintain flexibility and strengthen surrounding muscles.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFlex (Heat) vs. Flex (CD):\u003c\/b\u003e Flex (Heat) is for arthritis and joint pain with heat signs — redness, burning, swelling, and inflammation.

Histidine (an amino acid) removes excess copper and iron found in arthritic patients — eat foods high in histidine such as rice, wheat, and rye. Fresh pineapple contains bromelain — excellent for reducing inflammation. Increase intake of nourishing, cooling foods such as Mexican yam, yam, radishes, potatoes, carrots, melons, cucumbers, beets, turnips, malanga, celeriac, taro, and rutabaga. Avoid spicy food, caffeine, citrus fruits, sugar, milk, dairy products, and red meat. Fish oil may help alleviate pain associated with rheumatoid arthritis — can be taken alongside the herbs. Decrease sour foods, drinks, and citrus — their constricting nature may contribute to further stagnation in the channels and collaterals. Avoid spicy, pungent, and aromatic vegetables such as pepper, garlic, onions, basil, rosemary, cumin, fennel, anise, leeks, chives, scallions, thyme, mustard, chili pepper, and wasabi.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eTao of Nutrition (Dr. Maoshing Ni and Cathy McNease):\u003c\/b\u003e Recommended foods: plenty of fresh fruits and vegetables, dandelion, cabbage, mung beans, winter melon, and soybean sprouts.
