Why do I have a spasm/lump in my forehead 1 month post Botox? (photos)

I had some Botox placed in between my eyebrows for a “brow lift.” This was done a month ago. I’ve begun to feel tingling/tightness in between my eyebrows lasting 5-10 minutes. I looked in the mirror and it’s causing a visible distortion as well. It appears as a lump on my forehead and my eyes in an angry face, however I don’t have control to relax my face while it’s happening. It almost seems like some kind of spasm, but the muscles should be relaxed if I’m correct? Is this normal?
