What can be done for large noticeable nodules due to Sculptra injections gone wrong?

Hello, and sorry to hear about the issue you are experiencing. In general, the nodules should disappear with time. Aside from time, other things that may improve the appearance of the nodules are the following:1) Massage2) Steroid injectionsI would recommend following up with your surgeon regarding these options. I hope this helps, and best of luck.

These nodules resulting from Sculptra do typically resolve on their own over time, though this can take quite some time. Some other fillers can help to resolve the problem. I recommend visiting a dermatologist or board-certified plastic surgeon for the best options. 

In my experience with Sculptra, if visible nodules do develop, they normally do go completely away over time.  This can take 2-4 years to occur though.  If it has not been 2-4 years since your last Sculptra treatment, then it is possible that an injection of a steroid into the nodules can take them away.
