Illegal butt injections. Why is my but so warm? It has been like this for 10 years

Thank you for your question regarding why your butt is so warm after illegal silicone injections.
I believe your buttock is so warm because your mast cells are secreting histamine, which causes an  inflammatory response and heat. Basically, your body is trying to create scar tissue around the foreign body, in this case, silicone. After your body forms scar tissue, your body tries to break down or reject the silicone. Your body tries to eject the silicone through the skin. As your body makes a path or tunnel to the skin in order to eject the silicone, the skin becomes discolored. As your body breaks down the silicone into micro spheres, it is possible for the silicone to get into your bloodstream. It is extremely rare for it to get in your bloodstream then get into your lungs and kidneys. My suggestion would be to have this silicone removed as soon as possible. Since it is causing your problems, specifically a hot butt, as well as immune system complications, get this stuff out! A weak immune system is a major complication. Inevitably, this will lead to more severe problems. Get this fixed as soon as you can.
Before you make any decisions regarding an unknown substance removal, I would suggest you seek consultation with an expert. Please seek an experienced, board-certified, plastic surgeon. Travel out of state if you must to find such an unknown substance removal expert. If you have any more questions regarding unknown substance removal, or plastic surgery in general, please contact my office.

Hi Momma4health!

Thanks for sharing your questions—let’s break it all down:

1. “They say if you put this in your body it can get in your blood stream and infect your kidney and lungs. How?”
In terms of silicone or biopolymers (like liquid silicone, PMMA, or other injectable materials not approved for body contouring), the concern is migration and chronic inflammation. Here's how that can happen:

Not immediately in the bloodstream: When it's first injected, the material typically stays where it was placed (like the buttocks). Over time, your body may react to it—your immune system sees it as foreign and tries to attack it, causing chronic inflammation. This inflammation can cause the material to break down into smaller particles or trigger your immune cells to carry some of it into the lymphatic system and even into your bloodstream. Once in circulation, those particles can settle in organs like the lungs, liver, and kidneys, especially because those organs filter blood or lymph. That’s where it can cause problems like granulomas or organ dysfunction in RARE but serious cases.

2. Why didn’t it get in the bloodstream immediately after injection?
Because the particles are initially too large or trapped in tissue, they usually don’t enter the bloodstream right away. Only with time, inflammation, movement, or improper injection technique (like injecting into or near a blood vessel) can allow migration to happen.

3. “Why is my butt so warm? Been like this for 10 years.”
A few possibilities: Chronic low-grade inflammation: The warmth could be due to your body constantly fighting the foreign material. It's like a slow-burn immune response. Increased blood flow to the area from the inflammation or the body trying to "deal with" the material. Nerve sensitivity or fat necrosis could also give a sensation of warmth or weird sensations, even if you don't see obvious outward signs.

It’s good that you’ve had no complications aside from a weakened immune system, but that in itself is important—because your immune system is likely busy dealing with the material 24/7, it can leave you more vulnerable to infections or other illnesses.

If you're open to it, a consultation, whether it be virtual or in person, I am a board-certified plastic and reconstructive surgeon in New York 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 along with a third stage of reconstruction. This approach is designed to ensure the most complete removal possible while minimizing risks and optimizing patient outcomes. Please give us a call (516)279-2616 so our dedicated Silicone Coordinator can initiate and walk you through the process. She, too, has had silicone injected along with removal and reconstruction. She'd be happy to share her silicone journey and help you along the way with yours.

Best of luck on your silicone removal journey. We're always here if you need us.

Silicone in the buttocks and soft tissue can cause inflammatory
reactions. Our office specializes in the management of Karamanoukian
Grade I-IV reaction in the soft tissue using minimally-invasive means.
The first step is to identify the grade of soft tissue reaction and
determine whether the tissue can withstand surgery.
