Hi I have two questions about skin problems. 1. About a week ago, maybe even a little over I was bitten by either a fly or a mosquito. Unfortunately, I was scratching. I smeared with antihistamine ointment and everything would be okay if it were not for the fact that so far this bite can be seen. De facto redness fades, but very slowly. Practically imperceptibly, and so from day to day it is not visible. Is it normal for it to heal for so long? 2. Some time ago a rather persistent pustule popped up for me. I decided to smear it for the night with ichthyol ointment, unfortunately bad luck wanted that it was in such a place that I had to seal it with a plaster because otherwise at night I would get everything dirty. Now in the place where there were those parts of the patch with which it is attached to the skin from time to time appear slightly pink spots slightly darker than the skin. For example, not during the day but e.g. when I sweat or when I take a warm bath. You can't see it very well But the facts are that they show up from time to time. It's been about a week since it was sealed, if it matters. What could this mean? Best regards.
