Diabetes is an excellent guess, although those pinprick pains usually occure late
in the process, and aere symptomatic of
osteomyelitis, which can be life-threatening and result
in toe amputation, foot amputation, or leg amputation. Often these start in the tip, of a smaller toe, so the fact this is a single toe is significant. If the infection migrates to the bloodstream you may have ther patient end up with endocarditis and a pig-valve procedure. All this for a little pin-***** on the toe!
