There are a variety of different types of arthritis which are managed in differing ways.
Osteoathritis – many people experience this as they get older. This really involves wear-and-tear in the spine or joints which has become inflamed.
Rheumatoid Arthritis, Gout and other immune conditions – these conditions are really immune conditions affecting the blood – i.e. an over-reactivity of the immune system producing too many white cells and similar.
These systemic conditions need fine management with your doctor.
Osteopathy can be helpful to keep joints lubricated and mobile – gentle fluid treatment could help calm down the immune reactivity.
Joints which are affected are often under more load than they should be due to misalignments – balancing posture could help this.
