                                                          Burning sensations have several causes. Irritation or abrasion from clothing is the simplest, which will usually go away. The start of a rash or dermatology problem is another cause, especially if you changed soap or laundry detergent. Some such sensations might be the first stages of an outbreak of shingles. See a doctor if the symptom is severe or persists.
