Is it normal to have swelling in lower back after BBL six weeks post ?

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 :)

Thank you for submitting your question. A photo would be helpful.  It
may take up to six months for the swelling to subside and the true result seen. The lower back is normally very fibrous and the swelling will last longer in this
area. Discuss your concerns
with your surgeon. I hope this helps. Best wishes

During BBL the lower back and waistline is contoured to improve overall appearance. This can lead to moderate swelling and hence the reason for the garment. If the swelling is excessive or persistant it may represent fluid correction that should be aspirated. Please have you PS check the area.
