What is a mixed connective tissue disorder like?

Connective Tissue : There are over 200 disorders that impact connective tissue. Some, like cellulitis, are the result of an infection. Injuries can cause connective tissue disorders, such as scars. Others, such as ehlers-danlos syndrome, Marfan syndrome, and osteogenesis imperfecta, are genetic. Still others, like scleroderma, have no known cause. Each disorder has its own symptoms and needs different treatment.
