If there is a small lump after the injection it is best to massage the treated area and return to your treating physician to get examined. You can get a small infection or a granuloma at the injection site.
Sculptra lump or injection irritation.
It is unusual to have a bump occur a week after the Sculptra injections. I would suggest making an appointment with your doctor to have the bump checked out.
Expectations after Sculptra treatment
Nodules from Sculptra injections typically take a few weeks to develop. Best to follow up with your physician for an in-person evaluation to determine the best treatment for the area.
Sculptra lump or injection irritation?
Without examining you or seeing pictures of you, it is difficult to know what might be causing the lump on your temple one week after a Sculptra treatment. It would be unusual to develop a bump from the Sculptra as soon as a week after treatment. Normally those types of bumps take at least a month to develop. It is possible to have a bit of a bump at an injection site, but normally this would go down within a week. My best advice would be to contact the physician who treated you so that you can be evaluated in person.
