Sounds like you've got a lot going on. At least the sore arms are hopefully better today although my COVID booster was sore for a couple days. I need to get a flu shot still. I wanted to do it today but I have a migraine so can't drive to town.

Your doctor should should send your PT referral to wherever you want to go. At least that's how it has worked for me. Although when I had PT this summer the doctor wanted to send me to where "all her patients go" but was too far away for me to drive just for PT. I hope you can get in soon; your poor knee has been sore for way too long.

Hoping today is better than yesterday!
