Autoimmune Disease: Rheumatoid Arthritis
Usually our immune system works to fight invading pathogens. However  with an autoimmune disease our bodies do not recognize healthy cells and attack them. In the case of rheumatoid arthritis the body constantly attacks healthy joint cells. Joint pain, fatigue, and weight lose can occur. It is recommended to exercise and eat healthy to reduce these side effects of the disease. Only exercise for a little while each day though and try to eat anti inflammatory foods too. These recommendations should help reduce your pain overtime. There are other solutions and EDL encourages you further research into other options.
