Reagan's leg: next step

We still don't know anything.  We have an appointment scheduled for next Tues afternoon with a Dr Hayden at OHSU.  He describes his specialty on a web-site as: "I evaluate and treat a wide variety of bone and soft tissue (muscle, tendon, fat and ligament) conditions, including benign and cancerous tumors in the arms, legs, pelvis and spine."  He has received the MRI and has looked at it, according to the gal who called me.  I expressed my frustration in having to wait a week to hear what he thinks, and asked why he can't tell me something over the phone.  She just said, "Well that is not how we received the referral from Dr Achterman.  Dr Hayden wants to evaluate her in person and get all the information."  Sigh.  She also said that they may be scheduling a biopsy for the next day at Doernbecher's  Hospital (the children's hospital associated with OHSU).  So the wating and worrying continues.
