First of all, relax. I understand it is scary when a we have severe pain and aches esp in the head and face area. But please do not panic. There is nothing wrong with your jaw or your wisdom tooth. It just may be erupting a little out of path or maybe extending a mild pressure of the adjacent tooth. All you need to do is visit a dentist and get a complete mouth xray (OPG i.e., Orthopantomogram) done. It will show you the exact location of your wisdom teeth inside your jaw. Now, blowing air in the mouth after tooth removal is a risky move. It may damage the blood clot formed and even an air embolus in the wound which can cause you immense pain as you mentioned. Do not do that again if you ever get any tooth extracted. Do not worry about your lymph nodes. Human bodies are not as fragile as you think. Please do not worry.
Next Steps
Get an OPG from a nearby dental clinic
