Can diet help control my bursitis flare-ups?

Yes. Yes and no i suppose. Bursitis is an inflammatory condition of fluid filled pads near the joints. Anything that causes inflammation, such as overuse, can trigger bursitis. If you have a specific food trigger, you can help identify that by keeping a food and symptom journal. However, i'm not sure any food can control bursitis.
Yes. A diet that is designed to help bursitis should be centered around foods that help reduce inflammation in the body. Foods like whole grains, vegetables, fruits and fish such as salmon and tuna can help relieve inflammation in your joints and ease pain. Keeping yourself properly hydrated will also help keep your joints pain free. Read more: http://www.Livestrong.Com/article/284676-diet-for-bursiti.
