I have a recurring neck rash, accompanied by redness & itchiness, It comes & goes every few days; sometimes the itchiness gets intense, sometimes a little less itchy, but still very dry & flaky in the front of my neck. It happens only in June, July & August, for the past 5 years. I ve tried lotions, aloe & creams; they help a little but don t clear it up totally. Could it be allergy?
