Hi there ~
I understand your condition. I believe that there is a healing period post circumcision
. While the paleness could be normal it is not concerning to have the bubble like appearance along the portions that have been bruised. It is a part of the healing process. I believe you are taking antibiotics as prescribed and you should not be concerned. Follow the doctor's instructions and keep the area clean among others like has been instructed. You should do fine. If you believe there is cause for concern with the issue becoming worse, please consult a doctor. I hope this helps.
Take care and have a lovely day!
