That is quite an experience, at least you weren't hurt worse or killed. Congrats on defending yourself. Hang in there, man. I am not a dr or anything, but my 2c-- It doesn't sound like typical PN but it is different for everyone. If you have still not turned up with a disease, I think you need to try not to worry about this anymore. Do drugs like Tylenol and Advil help your pain? These help with inflammation and do not typically relieve PN pain. If it does turn out to be PN, there are effective drugs you can take to manage this. It is unfortunate to have to take drugs, but these can help you get your normal life back.
