Sharp Pain After Sitting - 2 Weeks Post-op BBL

At 2 weeks post BBL, it may still be normal to have pains, however it is always best to consult with your board certified plastic surgeon who performed the surgery. He or she will be able to advise based on your specific case. 

Hello dear!!
Thanks for the question and provided information as well.
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 :)

I think that with buttock augmentation the buttocks might be painful as you start getting back to your normal routine like sitting on the region. If concerned, best to see your surgeon.
