tooth infection... gaseous necrosis of the dental pulp

                        I read up and found that gaseous necrosis of the dental pulp was probably the cause of this pain, The only way to relieve this type of pain is to swish cold water around... It's been 2 hrs since this pain has started and hasn't gone away. The pain is feels so severe that it's scaring me a little. there is 5 more days still before i get my wisdom teeth extracted.  
does anyone have any advice on what i can do for the time being to slow the pain down??
will the pain go away at all?
any advice is greatly appreciated
