Sorry this happened. I do use monostat myself with success. You may have itched during the night and caused the swelling when already irritated. So, what about wrapping an ice bag in a towel and placing that on the area? I do take ibuprofen when in discomfort and it's known to reduce swelling/inflammation. So, you can try it. I'd say it's a better choice than Tylenol. Otherwise, just try to leave the area alone and the swelling should come down. good luck sweetie and let us know how it goes
