I have a burning sensation in my lower legs. Burning gets more severe when touched, even if only by pant leg. Area is a mottled

What you're describing goes by the medical terms hyperesthesia, allodynia, and/or neuropathic pain.  Hyperesthesia refers to unusual sensitivity of skin to stimulation while allodynia refers to pain resulting from a stimulus which would not normally cause pain.

This can result from vitamin deficiencies and/or long-standing poorly controlled diabetes.  One complication of shingles (reactivated chickenpox) is post-herpetic neuralgia, which is hyperesthesia and allodynia of the affected area.

Tricyclic antidepressants, serotonin-norepinephrine reuptake inhibitors, capsaicin, and some anti-epileptic drugs are sometimes used to treat (neuropathic) pain rather than chronic narcotics.

Best to see your family physician for a complete & thorough evaluation.  Good luck!

Thank you for the response. I have been tested for diabetes, and while not diabetic, I am hypoglycemic and carry a meter to check my sugar. I don't know if it is relevant, but I am 10 tears post op from gastric bypass surgery, which might contribute to a vitamin deficiency. I also work as a security guard and walk at least 20 to 28 miles a day.

Once again, thank you very much for the response.
