Knee better, chest worse.......

Well my knee is getting better.  Im seeing alot of progress.  My ROM is up to 70 degrees and I can walk on ONE crutch in the house!!!  I was talking to the PT and she said it be slow but once the progress started it would start snowballing and now I can actually see that.  My chest is alot wrose....I feel like Im drowning.  Im sure some solumedrol and a 'z' pack wounldnt hurt but not really in the mood to go to the hosptial right now.  Well Im going to end this.  Im jittery from the nebs.
