Will the Nickel Size Lump over my Right Eye Dissipate over Time After Botox?

First ask your physician who is best qualified to answer your question. My educated guess is that it is a small hematoma which may take 3 weeks for this to soften and resorb, possibly longer. In some instances they can be aspirated.

As pointed out, there is a possibility of bruising after any injection treatment (hematoma).  With that said, it would be a bit unusual to not have any indication of bruising.  If the bump persists past 3 -4 weeks than have it check out.  Alternatively, call your injector and have them bring you in now for peace of mind.

immediate lumps after dysport or botox means one of two things. You have a localized amount of the injected product that will be absorbed within a few hours, or there is a contusion/hematoma colleciton of blood fromt the injection. That too will decrease on its own but see your doctor to be sure.

It is possible that you have a small hematoma or blood collection, but without an exam I can not say for sure.

If it is a hematoma then it will go away with time.

Each time you get injected, there is always a small risk of bruising.  What you are describing sounds like a bruise that occurred with the injection of the BOTOX.  These bruise do go away.  There may be a slight tenderness with this but it should be getting better each day.

You should get it checked by your doctor, but if you have a lump after BOTOX it may be a bruise and that usually goes away.

Since it has been over 9 days, I doubt it is a residual Botox solution injected. My guess is a collection of blood or hematoma. But you did not state any black & blue, so maybe it is a cyst that has become more noticeable after receiving Botox. Seek medical opinion.

The lump after Botox is most likely a bruise or small hematoma that developed after injection.  This can happen to anyone at anytime.  This should go away over the next week or so.

  This sounds like a hematoma. Your physician inadvertently struck a blood vessel when performing the injections. Unlike the crow's feet area where one can usually visualize the blood vessels, or the glabella where one's knowledge of anatomy can guide the injector away from the blood vessels, the forehead can often be more of a hit or miss situation. Unfortunately, in your case it was more of a hit.

   Fortunately, like any bruise, this will dissipate in a matter of days or worst case, a week. If it does not I would return to the physician who injected you.
