Hello,
Red sore at the back of the leg with stinging sensation is commonly caused due to high sugar intake,
diabetes, poor hygiene, obesity, stress, irritations, abrasions, tight clothing, etc. You are suggested to cut on sugary products and carbohydrates. Avoid oily, spicy, junk food. Cut on addictions if any. Take care of your hygiene. Wash the
carbuncle with warm water. Warm compress is effective.
You can take
Acetaminophen or
combiflam, one SOS when needed. To prevent the spread of infection you may need a course of antibiotic like Ampilox -500 or
Augmentin. It will get drained by itself. If not, visit ER and get it drained, cleaned and managed. Do regular exercise, maintain a healthy BMI.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
