Claudia:
I have been using Botox close to thirteen years and never have seen persistent lumps. We typically advise our patients to be off of all anti-inflammatory medications and aspirin products two weeks prior to any injections to minimize the risk of bruising. It sounds like this most likely represents bruising at the injection sites. If it is bruising that is causing the lumps, then I would expect to see this clear up with time. I would advise you to follow up with the treating physician.
Thanks for your question.
