Great news about the referral to get an appointment! But talk about fair weather friends.... there's something I'd add to that to tell them but it's not appropriate.

However, if there were only good things to say about our lives, it wouldn't be life, good with the bad and all. Your luck is changing already with the referral to see the specialist, good news!!
However, bad with the good now; I'm SO sorry to hear about your tendon, but glad it is not completely torn, that is good news. I tore mine once and the doc said to definitely stay off of it, to use those crutches, and to prop it up whenever you can, and iced. I found lying on my side was easier by having it up on pillows between my legs, rather than on my back propping it up; it seemed to put less pressure and weight on it. Wishing you a VERY speedy recovery! Hang in there!! This will pass.
