After Botox injections for crows feet, I cannot close my eyelids fully or cry properly. How long before the effects wear off?

The effects only occurred after a followup injection three weeks after the original injections. I got two more 1 unit injections in two places under each eyelid. Is this a result of the followup underlid injections or a combination of both? Can I speed up the recovery period eg; exercising eyelid muscles, applying heat to the area to stimulate blood flow and flushing out the toxin, electric stimulation to activate muscle activity? Does recovery time start from original injections or followup?
