September is Arthritis Month in Canada. There are many myths surrounding this debilitating disease. Arthritis is not an “old person’s disease”. In fact, 60% of the 4.5 million Canadians with arthritis are under the age of 65. Arthritis is not a single disease. There are more than 100 different types of arthritis. Arthritis is a costly disease, costing more than $4.4 billion annually in healthcare expenses and lost work days.
