Hi there,
There has been no direct link found between rheumatoid arthritis and fibromyalgia. Both are relatively common so a person can have both conditions. There have been increased incidences of fibromyalgia among people suffering from rheumatoid arthritis. Having rheumatoid arthritis can be considered as a risk factor for fibromyalgia. A lack of vitamin D is associated with higher risk of rheumatoid arthritis. A correct intake of vitamin D, along with calcium is very important in protecting the health of our bones. Low vitamin D may lead to early progression of the disease. You need to see a specialist. Your doctor will advise you to start vitamin D supplements. In fibromyalgia medicines should always be used along with exercise and behavior therapy. Medications like Duloxetione, pregabalin and Milnacipram have been approved for treating fibromyalgia. See a psychologist for conselling. It will be best to discuss it with your doctor about which medication will be most suitable for you. Do keep us posted.
Best luck and regards!
I take anti-inflammatory (boswellia serrata, turmeric, sea buckthorn oil) supplements for pain and glucosamine with chondroitin for my joints. Juicing vegetables also helps.
