Botox Dilution, Would that Cause Botox to be Lumpy?

When those doctors who dilute their Botox with larger volumes of saline than other doctors, they must also deliver greater volume in the injection to deliver the same number of units. They may choose to mix it this way to give them a more even and wider-spread result or they may find it too difficult to inject tiny amounts of liquid when using the more concentrated Botox. If they do use the larger volume, then the botox injected will cause temporary larger fluid bumps. These do go away soon but it may make going right back to work difficult as makeup doesn't hide bumps.

The good news is, Botox "lumps" are temporary and nothing to worry about. They have to do with the fluid used to dilute the Botox for injection, since it comes as a powder, and they will absorb into your skin quickly and go away. Sometimes they appear more than others, but it is nothing to be concerned about.

On the contrary, visible lumps of the hyaluronic acid fillers (Restylane, Juvederm) are an issue that should be addressed by your physician. It's normal and often fine for lumps to be FELT beneath the skin after treatment, since sometimes they provide important scaffolding for a deep line, but lumps should never be visible to you or someone looking at you.

Whether Botox is diluted more is probably not as important as if the injection was too superficial.  When the liquid is injected that volume will cause a "welt" and is more apparent if too superficial.  Either way, it should go away quickly.  If you had a small area that bled due to the botox you may have a small area that will bruise and take some time for the bump to go away as the blood dissolves.  The good news is that it should not be permanent.
