Thank you for sharing that. Tt takes courage to reflect honestly on past decisions. Since it's been 11 years since your butt injections, it's definitely worth having a deeper look at your situation, especially if you’re unsure of what material was injected. If you're unsure of what was injected, that’s the first major concern. There are a few common types of substances people have had injected: Medical-grade fillers (for example: Sculptra) generally safe when done properly. Silicone/Biopolymer (liquid form) — Not FDA-approved for body contouring injections and can lead to serious complications over time. Often done illegally. These materials can migrate, cause chronic inflammation, infections, and other serious issues. If you're experiencing any symptoms such as pain, firmness, lumps, skin changes or discoloration, infections (recurrent), or any shifts or migration of the material in the buttocks to any nearby areas, this is definitely cause for concern. However, even if you’re feeling fine now, complications from silicone/biopolymer injections can sometimes surface years later. The first step would be to consult a specialist such as a board-certified plastic surgeon (especially one experienced in silicone/biopolymer removal) who can assess the situation and advise you on monitoring or removal options. Second step would be to go for imaging. An MRI with silicone protocol can help determine if any foreign material is present and whether it's causing tissue damage or migration. Don’t Wait for symptoms.  Many people wait until things become painful or dangerous. Early evaluation gives you more options and better outcomes. These substances don’t naturally dissolve. Your body can mount an immune reaction to them years later. Complications like skin breakdown, hardening, nerve pain, or even systemic illness (autoimmune-like symptoms) can appear after 10+ years. Yes, it’s wise to be concerned and proactive. Just because you haven’t had problems yet doesn’t mean they won’t happen. Getting evaluated by a knowledgeable surgeon and having imaging done is the best next step.
