bad news in son's mri

Well, heard from my son's doc today. He has a completely torn ACL.  So, that means surgery for him.  He sees the ortho on Monday.  Poor kid. He is 13 years old and has two surgeries already.  More than I had at that age!  He won't get to start the basketball season, but hopefully the coach will let him start when his knee is healed.
Since the awful fight with my husband, my leg quit working again!  Right leg is weak and tingly and I have drop foot.  It is so weak that it just drags along like Quasi Moto in The Hunchback of Notre Dame.  I came to work on just my cane, but I can't make it thru the day with that. I borrowed a wheelchair from the nursing services that adjoins my office.  Luckily that is there.  I have tried to walk and it just takes forever and is too exhausting to get 10 feet.  Last time my leg was this bad, I was in a "flare".  I have to literally pick it up with my hands in order to get it into the van. 
Lots of doc appts in the future for me and my son.  Hoping I get some answers for me!
