What Does This Blood Test Result For Burning Sensation In The Groin Area Indicate?

My wife is 47 years old. She had a flu shot last November. Not long after she had pain under her one arm pit. Then both arm pits. She is an RN on a pediatric floor. Upon returning home from a trip to Alabama from Michigan for Spring Break and working 3 12 hour shifts in a row she started to have a burning and tingling sensation in her groin area. This was on the inside of both legs. She then started to have tingling and numbness in her feet, she also has that sensation in her arms and fingers. She will also get a burning feeling on her scalp and other parts of her skin that is brought on by touch or contact with clothing or purse straps etc. She had a full MRI that showed nothing wrong. She had a bunch of blood tests and was low on B12 but not super low. She was tested for Lyme Disease and it came back negative. She did have a positive test for Autoimmune. She has since started eating a Paleo diet but it does not seem to have helped much. When she works the symptoms seem to come back quickly. She has also gone to see a neurologist, and a homeopathic doctor. Neurologist wanted her to take steroids and Lyrica and she did not do it. She does not want to mask the symptoms. She wants answers not a pill temporary fix. Thanks
