Our nerves are having a hard time with these infections. I think you are experiencing neuropathy.
My skin sometimes feels like sunburnt, on other days, the water falling on my skin while showering is too much. Or pins and needles, crawling feeling under the skin, numb parts of your body.
I sometimes get help when injecting B12 (be sure to only use methylcobalamine or hydroxocobalamine), you could give that a try.
