There are two situations where I can have random moving stabs/pin pricks or sensations, or burning.

1) I had some all over burning once when I had a mild flu...about 3 yrs or so ago. I blocked it with aspirin in the form of AlkaSeltzer. I think anything that increases inflammation...will increase the pain stimulating molecules for some people.

2) when a weather low pressure system moves in over me, I can have pain in MANY places, arthritic and PN... many of us have increased discomforts during severe weather changes.
Not everyone reacts to LOWs however. My husband hates the HIGHs...which I feel better during. (his is mostly sinus and back pain then).
