2. osteoarthritis and rheumatoid arthritis
Both of these cause pain in the joints and difficulty to move, among other symptoms. In the case of osteoarthritis, which is common among elderly people, the constant wearing of the joints due to effort, movements, and carrying weight, erodes the soft tissue between the bones.
As a result, bones can bump into each other with movement and cause pain. Rheumatoid arthritis is an autoimmune disease, where the cells of our own immune system attack the soft tissue of the joints. This tissue becomes inflamed and tears, causing pain and difficulty to move. Both rheumatoid arthritis and osteoarthritis are known to increase the chances of developing fibromyalgia, although the actual connection between these conditions isn’t yet unveiled.
