Some type of liquid injected in my butt. What do you recommend I do?

I recommend you visit a board certified plastic surgeon buttock implant specialist for a physical exam to determine if surgery is imminent to start removing the unknown liquid or if you can wait for problems to arise. Unfortunately I see at least 1 - 2 patients per week with this exact same story. There is a protocol I use for treatment depending upon the severity of symptoms. Glad to help.

Thank you for your interesting question. That is very concerning that you had some unknown substance injected into your buttocks several years ago. Fortunately you have not had any foreign body reaction, infection, hardness, or systemic effects. I would consider yourself lucky and urge you to visit with a board certified plastic surgeon if you are considering any type of buttocks augmentation. Your doctor might also order an imaging study to evaluate the substance in your buttocks (ie xray, CT scan, MRI).
