About a year ago, Linda began to feel numbness in her feet, which gradually worsened, becoming uncomfortable and ascending to involve the distal leg; the discomfort gradually transitioned to pain.
She had been relatively active, walking about a mile to work every day and biking frequently during warm weather. She has recently begun using a cane to help her walk.
Over the last 2 weeks, the pain has gotten progressively worse; it is now intense and burning, and is accompanied by tingling and prickling sensations. Constant for most of the day, the pain is more intense at night and disturbs her sleep.
Her pain has caused her to miss work, and she is wondering if she should take a leave of absence.
She is also worried about weight gain because she is not as active as she used to be.
Linda also states that her discomfort has affected her enjoyment of family and social activities. She no longer participates in university social functions or activities with her family. She has canceled her vacation plans for next month.
On preliminary physical examination, Linda does not appear to have any pustules or rash, nor does she report any outbreaks in recent months.
Examination of her feet reveals a symmetrical pattern of foot pain that is not increased by stimulus.

The most probable cause of pain is Diabetic peripheral neuropathy.
