Severe upper eyelid ptosis after Dysport! Will it get worse before getting better? How long will this last? (photo)

I received 20 units of Dysport 6 days ago for mild forehead and frown lines. By the 4th day after treatment, my left upper eyelid started to droop. I called the doctor, who prescribed me apraclonidine drops, which only slightly helped. Today (6th day after Dysport) my left eyelid is completely droopy! How much worse will this get? Will it completely reverse? When can I hope to start seeing some improvement? Should I try to rest that eyelid, or should I try to exercise the muscle?
