You and Lucas are both in my thoughts. I'm so sorry either of you has to go through this. Hopefully things will pan out for an MRI thanks to the help of others on here; it may bring you some comfort to have a definite answer so you don't have to second guess yourself.
Despite all this, Lucas is an awfully lucky guy to have you looking out for him.
