Glad you're getting some relief.
A caution from someone with serious allergies: sometimes what starts as a mere skin reaction can explode into a much, much more serious systemic reaction very suddenly. If you must continue using the topical medication that is causing the reaction, be very alert to any worsening of your symptoms, especially tightness in your chest, coughing, wheezing, itchy eyes, throat irritation, new spots of itchiness, or dizziness.
If any of those happen, chew up 50 or 100mg of benadryl and wash it down with warm water, then call 911 or get to an ER pronto.
Many allergic reactions remain local and relatively benign. But, when things go wrong, It is amazing to see how quickly allergic reactions can progress from a niggling annoyance to life threatening drama. Best of luck.
