I just had Dysport injections on my forehead, not my first time. Will this lump go away? (Photo)

You may have hit a vein or gotten swelling. Id consider warm compresses and wait 7-10 days before considering seeing your physician, it should resolve.  Best, Dr. Emer.

Chances are that you developed a deep bruise or small hematoma.  This should resolve with time.  I would wait a couple weeks for this to resolve.

How long ago did you have Dysport injected? Are you having any other symptoms, such as pain or drainage? If this persists longer than 3 weeks, I would make a follow up appointment to have it evaluated.

This is not normal. It is possibly a hematoma, collection of blood under the skin. There is nothing that can be done but your doctor should know. It should go away within a week. This was caused by the injector nicking a blood vessel in the area. Careful injectors can prevent this, or minimze the consequences if recognized immediately.

There is always a little bruising and swilling after an injection.  If it persists longer than 10 days please contact your doctor.

Yes. Sometimes there is a bruise under the skin. This is normal after dysport or botox give it ten days from injection. 

Small little bumps immediately following Dysport are usually due to the liquid from the injections.  Whereas, tender areas of swelling following injections usually show bruising because they are due to small regions of bleeding beneath the skin.  These usually resolve within a week.

Is the bump painful or hard? How long ago was the injection?  It is probably a vein that was hit during injection.  It should go away gradually.  If it persists more than 10 days I would call your doctor for further instruction.
