Can Strenuous Excercise (Inversions) Cause Botox Migration?

I sent in a question about botox around my eyes and the droop in my mouth recently. I think I figured out what went wrong but wanted to double check my 'self' diagnosis. Right after botox, I went to a yoga class where I did inversions (upside down with blood and pressure in my head/face) for awhile. Stupid of me, I wasn't thinking! I am sure this is what may have caused the spread. Is that possible? If so, could it have migrated internally toward my brain? Sounds silly, but nervous??!
