My left eye keeps tearing after Botox injection. Please help and advise

There is no research to suggest that long-term use of Botox may result in bleeding disorders, or result in any long term systemic effects for that matter. You need to see your primary care physician for assessment.

I would go back to the doctor that injected you and let him look at the eye.  It is not normal to have such severe drooping of the eyelid and double vision.

I suggest speaking to a well trained cosmetic dermatologist, there are options such as fillers, but sometimes Thermi is best for a more long term cure.  Best, Dr. Emer.

The skin and muscle layer is extremely thin around the crow’s feet, hence blebs or little bumps are normal and to be expected after Botox injections in this area. These bumps are just fluid under the skin which gets absorbed by the body and should flatten out within about 20 minutes.

It often requires more units in some people and remember it is a "reduction" not permanent paralysis. Sometimes fillers are needed as well.  I suggest seeing a cosmetic dermatologist with experience in neurotoxins and fillers.  Thermi is a permanent solution or trying dysport or xeomin...

Yes and no. Generally Botox is not injected directly into the creases under the lash line. However, when Botox is injected into the Bunny lines and crow's feet, it secondarily works to diminish muscle pulling under the lash line resulting in a softening of these creases.
