My Teen is an Old Lady Who Turns Purple (& her little brother has arthritis, too)

*My 13 yr old is an old lady that turns purple* My 13 yr old daughter has Mixed Connective Tissue Disease, (Lupus) which means multiple overlapping autoimmune diseases. She has Dermatomyositis, & Juvenile Arthritis. Yup, arthritis. She turns purple when her hands and feet get cold, which can happen from A/C. She was first diagnosed at age 6. My 11 yr old son has Psoriatic Arthritis. All of these are Autoimmune Arthritis. We share so you can learn!
