Are lumps on my forehead a result of my last Botox treatment? (Photos)

I have been getting botox for my migraines for 2 years and have never had a reaction. About 4 or 5 days after my last treatment(2 and a half weeks ago) a giant lump formed above my eyebrow, it went away after 2 days but other lumps have been forming and going back down on my forehead and hairline since. My eyes also swelled from days 5-10. My neurologist said it had nothing to do with botox when I contacted the office, and she did not want to see me, but I feel it has to be related to my botox.
