I had flea bites on my hips and bum and itched the hell out of a few. I woke up today and noticed that there is a line of purple broken blood vessels (straight lines, you can see almost exactly where my nails were). This has happened before when I itched too hard. Can anyone ease my mind and let me know it's normal? I just got back from a discouraging doctor's appointment and would love to avoid that place at all costs. Thank you!!
