If you have butt tingling and aching 1 week post op after BBL, is this a good sign that capillaries and blood vessels are formin

Hello dear!!
Thanks for the question and provided information as well.
Yes, this means the nerves are healing. You are still early on the healing process, it can take up to six months to see your final results, so please be patient. At the stage you are in, inflammation, discomfort and irregularities are normal.
If you have any concerns, please follow up close with your plastic surgeon.
Good luck :)
