Since the weekend began, dad's leg pain has been at an all-time high and has made it impossible for him to continue with rehab to walk. He's on his way to the ER now to have the leg scanned again so that we can figure out if there's something we can do to alleviate the pain.
Update: More bad news. The tumor in his leg grew so we're trying another surgery to cut off blood supply to it. The tumor can't be cut out because it's vascular.
