When my sister was experiencing constant lower back pain for several months, she had no idea she was having dural ectasia symptoms. This is something neither of us had ever heard of before.
Her doctor confirmed this with an MRI, and said that the best thing she can do is manage the pain. Sometimes she also has pain in her legs as a result of this.
Many people suffer from lower back pain, and there are many different reasons for their pain, but it has been frustrating for her because there isn't really any type of surgery that is being recommended. Hers is not an extreme case, so she has to learn how to manage her pain on a daily basis.
