Suggest Treatment For Peripheral Neuropathy And Numbness On Toes
Usually gradual
Detailed Answer:
I read your question carefully and I understand your concern.
Usually the evolution of diabetic neuropathy is a gradually progressing one, it is not typical to have sudden changes overnight. However in the case of sensory symptoms it is a subjective issue as it is difficult to quantify such symptoms objectively, can't be done through direct physical exam, depends on the subjective perception of the patient. If there are any doubts nerve conduction studies help to confirm the diagnosis.
Also I suggest a possible issue with peripheral blood circulation to be considered, which also can contribute to the altered sensation. Diabetes damages the arteries so such problems are common in diabetic patients. It is evaluated by your doctor through pulses on the feet, local temperature and if there are suspicious changes ultrasound imaging may be done.
