Hello Nani_1, I’m sorry for the adverse symptoms you are experimenting. I recommend setting up an in-person consultation with an experienced plastic surgeon for evaluation and possible removal of the Biogel injected into your buttocks. An Magnetic Resonance Imaging (MRI) scan may be necessary to evaluate the location of the injected material. The treatment varies from patient to patient, since no two cases are exactly the same. This may range from surgical excision, to hyaluronidase injection followed by VASER Liposuction and fat transfer into the area to correct the resultant deformity. Moreover, I strongly suggest you seeking medical attention immediately if you experience problems such as difficulty breathing, chest pain, signs of a stroke (including sudden difficulty speaking, numbness or weakness in the face, arms, or legs, difficulty walking, face drooping, severe headache, dizziness, or confusion), as it may be a life-threatening situation. Good luck and may God bless you! Dr. De La Cruz.
