I know how you feel. Worrying about this.

It is very hard to say. Some people are prone to autoimmune reactions following viral illnesses, and some injections and vaccines. This has to due with nerve tissue damage, and then the body makes antibodies to the nerve receptors and causes inflammation. Vaccine injury is the most common form of this.

People who genetically have specific markers may be more prone to this type of reaction. We had a fellow here who had a reaction to H1N1 vaccine. He was from Canada, and his doctors gave him steroids to take down the inflammation.

You could test yourself with therapeutic dose aspirin, for 2 or 3 days and see if you are better. That would reveal an inflammatory process going on. Some of our posters here use aspirin 500mg a dose useful. Just be careful with it, and get a good brand that dissolves quickly. There is a new Bayer fast dissolve here, but I don't know if you have it there. Take aspirin with lots of water.

I wouldn't expect doctors to be very helpful as they know very little about these injections, etc.

As I have mentioned before, some PNs resolve on their own. They run a "course" of sorts.

Don't get so stressed you make yourself worse!
