Didn't the surgeon see to it that you were given a paper on Autonomic Dysreflexia? It explains a lot of the symptoms you have with blood pressure, chest pain, headache ... It's potentially lethal if not treated correctly. When you feel your blood pressure going up and pulse rate going down you have to sit up - opposite of what you feel like doing. I carry a card in my wallet. There is a lot of good reliable information online and cards you can print, from respectable websites, not just forums.
Swallowing problems are the norm with ACDF. Nerves are damaged when the surgeon uses metal retractors that pull the neck apart and the esophagus and trachea aside so he can see. I was on tube feeding for weeks after my surgery and couldn't swallow anything but soft stuff for months. My swallowing still isn't normal after 2 years, but it wasn't good before either.
I have the neck and shoulder area plus shoulder blade area and bicep pain. I haven't been able to find out definitively what causes it, but it seems like a neck/nerve issue. It doesn't ease up.
Do you have the freezing and burning feeling in your feet and legs? I'm super sensitive to stepping on anything cool, like a tile floor barefoot. Legs hurt, but on EMG testing there's nothing wrong with the nerves there. Pain issues like this are commonly from central pain syndrome see
www.centralpainsyndromefoundation.com A lot of doctors will mention central cord syndrome, but completely ignore central pain syndrome. Sorry, but there's no cure for this.
Migraine headaches, possibly part of the autonomic dysreflexia, seems to start at joining of neck and skull and radiate over to front.
I have a pain doc, so at least I'm not wasting money in the ER all the time, looking like a drug-seeker. I've had multiple injections and ablations, but they are not working anymore. Even this doc doesn't want me coming but every 3 months. I wouldn't dream of letting an NP try to treat me. Surgeons, even my family friend, give up after they have done their thing. Rehabilitation doctors, physiatrists, are woefully ignorant of what to do for us too.
I've found helpful information from others with the same problems at

I live on hydrocodone, tramadol and Zofran and sometimes Klonopin or Valium for leg spasms. It's no cure, but helps with my "real" pain from bone spurs and arthritis in my spine pinching nerves. I call my leg pain, which is caused by damaged nerves in my neck sending mixed up messages to my brain, my head pain or not-real pain. Nothing touches it. See comments from others in the central pain forum.
