Am I at risk for further health issues after PMMA injections?

Thank you for being open about this. You're absolutely not alone in feeling uncertain or even scared after learning more about silicone injections. The truth about silicone injections (non-medical grade or black market, free liquid silicone injected into the body), especially in large quantities and not inside a medical-grade implant is considered very high-risk. It's not FDA-approved for body contouring or buttock augmentation. Complications may not happen right away. Sometimes they appear months to years later. Some potential risks include - Migration (the silicone moves to other areas of the body. For example: thighs, back, groin folds); granulomas (painful inflammatory lumps); infection; tissue necrosis;
autoimmune-like symptoms (chronic fatigue, joint pain, etc.); skin discoloration or hardening.
However, many people have had silicone injections and never develop serious complications — especially if the volume was relatively lower and they stop early. That said, your body’s reaction is unpredictable. Stopping now is your best move. The more product that gets injected, the harder it becomes to remove later, and the higher the risk of systemic issues. I recommend consulting with a Board-Certified Plastic & Reconstructive surgeon who specializes in silicone/biopolymer removal and silicone disease so they can assess where the silicone has settled, ff there are early signs of issues, how to monitor your health moving forward, and get baseline imaging done (typically an MRI with and without contrast - standard silicone protocol). It's important to watch for symptoms, such as: persistent pain or swelling, skin changes, hard lumps (nodules), fatigue, brain fog or joint pain.

I am a board-certified plastic and reconstructive surgeon with a specialized focus on silicone and biopolymer removal. Over the years, I have dedicated my practice to safely addressing complications arising from these materials. Recognizing the unique challenges they pose, I developed a two-stage surgical excision process and a third stage of reconstruction (often referred to as a reconstructive BBL). This approach is designed to ensure the most complete removal possible while minimizing risks and optimizing patient outcomes. I'd be happy to see you for a clinical evaluation whether it be a complimentary virtual consultation or an in-office appointment to discuss your options. My Silicone Coordinator has undergone silicone removal and reconstruction and would be happy to get the ball rolling to see how we can help. (516) 279-2616

Silicone biopolymers are being used throughout the world for facial and body volume augmentation. Results are longer-lasting that Juvederm or Restylane. 
Bellafill and Artefill are known to cause granulomas and permanent nodules with swelling. This is not the case for everyone. Silicone biopolymers can also cause similar chronic inflammatory conditions. 
In my practice, I specialize in the removal of Bellafill and Artefill injections, in addition to silicone biopolymers, from the face and body. Initially, treatments are non-surgical with corticosteroids and immune modulators. If unable to be corrected, we can also perform surgery in some cases. 
Silicone biopolymers can also be removed from the body if there are signs of migration or inflammation. All of these filler-types should be removed as early as possible. 
Lastly, our office is conducting ongoing studies of plasma-assisted corticosteroid application, which allows for diffusion of the treatment medication in superficial tissue without causing atrophy.

Certainly, it would be difficult to predict.  Open surgery with direct excision is effective as it allows removal of the offending agent without additional or surrounding fat removal or deformity.
