I've had Botox twice in my life injected between my eyebrows and just above each eyebrow. 1st time I had it I had slight swelling/bruising that settled within a few days which I assumed was normal. The last time I developed huge swollen hard lumps at each injection site. My face swelled so much I looked unrecognisable. My injector said I had an allergic reaction. He prescribed me with prednisone, my face went back to normal within a week. Can I be tested to see if I would react badly to Dysport?
