I went back to the doctor on Thursday. She got me to take off my jacket and scarf and felt my neck and shoulders. She tried to pull my shoulders back, which hurt like hell, and then said that the muscles have all completely seized up so she's not surprised I'm in so much pain and struggling to move. It's also no wonder the Diazepam wasn't working. So she's more than doubled the dose, warned me not to drive when taking it, and told me to call the physio team again to let them know I had to go back...
