Hi everyone,

My sister WAS a juvenile osteoporosis patient. She has grown out of it and her doctor has said that her bone density is in the healthy range. Just about a week ago, she began complaining about lower back-ache, stiff joints, etc. She has been doing more rigorous exercise recently. We saw her osteoporosis doctor today and he says her problems are not bone-related. He has told her she must see a rheumatologist and a neurologist. She basically cannot walk - she experiences no pain when she does walk, but her joints are very stiff, upto the point where it is difficult for her to keep her toes flat, etc. What is happening? I have been researching various types of arthritis. However, artritis involves pain and she has no pain whatsoever.

I am very worried. When the doctor said she had to see a neurologist as well, I got very worried and jumped to conclusions. Please give me advice and tell me what you think it is.

Thanks in advance.
