Can you offer info about my spasms and cramps after Botox?

I had Botox injected into my forehead from hairline to glabellum Feb 18th. 30 units. For the last few weeks I've experienced cramping and spasms in my 11 area. The cramps can be felt down to the middle if my nose. If I look in the mirror you can see my muscles contract and distort. If for instance I put pressure on the area it also triggers this. I did consult my injecting doctor about this with no answers. Any info would be helpful here.
