I am not suggesting you are taking Antabuse. This drug which was used to treat alcoholism, causes the same symptoms as a hangover... it increases aldehydes which is part of the metabolism of alcohol. The same thing happens in people with genetic problems with thiamine. Flooding the body with alcohol during binging produces the same types of symptoms.
It is mostly the aldehydes causing the symptoms. The alcohol itself is short lived in the body. The metabolic junk created, therefore is the real culprit.

Anxiety causes changes in breathing and hence, increases in parathesias in the periphery. Anxiety often leads to hyperventilation.

Reading on the internet is not going to give you exact symptoms that you may have. Everyone is different genetically and if you have defects in specific areas of metabolism, your symptoms with heavy drinking will vary from others who may not have the same hand of cards.

Your headaches may be due to many other things too. That would be a task for your doctor to figure out.

But for now, quitting the alcohol is your first priority. Take it one step at a time.
