No Chiropractor is going to jump on anyone's back with their knee!
The upper back, neck, and shoulder pain is normal. That was my worst complaint following my surgery.
You need to gently stretch it out, use heat, maybe gentle massage, if your Chiropractor uses a mechanical adjusting instrument that can help considerably.
Valium isn't going to help--you need gentle physical activity, not a sedative.
The sooner you can get active, within your reasonable boundries, the sooner you'll get over this.
My Chiropractor used stretching, gentle massage and electrical muscle stimulation all of which was very helpful....I can't agree more with getting active....I started to hold my arms out to the side and rotate them forward then backwards as I walked and that helped a great deal as well.
