i had the same issue at one week with the stinging. The nurse told me the stinging and itching feeling of the scars is the healing process, which went away by week 2. I took clarityn antihistamines which worked like a charm. It’s totally normal what you are feeling, it usually settles down by around the 2 week mark. As long as you don’t have any discharge/bleeding/strange smell or redness, the incisions should be fine. My tightness started easing at around 2 weeks, but still a bit tight as I had unders, not as bad as the first week though.
