Hi there, I received 30 units of botox one week ago for frown lines. Began to feel heaviness in eyes and eye strain about 15 min after the injections but subsided about 15 minutes later( as it had the last time I had botox last year. However, this time, on day three, the eye strain presented itself again. When should this eye strain/eye pressure/light sensitivity go away!?? Hurts to use computer, drive and go outside! Help! I am unable to revisit the Dr who administered the botox as I was just visiting that city last week. Thanks.
