Botox is temporary and therefore the undesirable side affects that you are experiencing will wear off in 3-4 months . If you wish to continue using botox , i would recommend that you seek out an experienced doctor/nurse injector to do your treatment. Best of luck
Botox is not permanent and will wear off in 3-4 months. My suggestion is to see a different physician injector if you decide to have treatment again, since this complication is rare and technique dependent. Best, Dr. Emer.
Botox is not permanent, so what you are experiencing is the temporary affect of it wearing off in certain nerves and not in others. Normally, this is when someone would get a re-treatment, which you obviously don't want to do. As the Botox wears off entirely your nerves will be back to functioning completely. Nerves that may have had more Botox injected to them (such as the part where you had droopiness) will take longer to come back than other areas simply because more neuromodulator was injected in that area.

It is very unlikely to get any permanent side effects or nerve symptoms from Botox. Though it is not unusual to get temporary eye droop if some Botox leaked into the supraorbital foramen (on the brow) and then gets down to the muscles involved in keeping the eye open. This side effect always resolves as the Botox fades, but can be improved faster with use of an eye drop your doctor can prescribe called iopidine or aclopidine. As far as tingling sensation, that sounds like nerve irritation, which should also go away often within a week or two of the treatment.
