hello and welcome to hcm forum,
i would be glad to answer you query, according to the history presented by you it seems that you had a bad experience, botox
if injected on a wrong site or in huge amount , it can result in a frozen look .
also, sometimes due to a wrong injection site, upper eyelid droops, squashing your eye temporarily.
i have not seen you clinically therefore cannot rule out the diagnosis, but in order to relief heaviness you can take a painkiller, just be calm .
use 0.5%Iopidine eye drops(1-2 drops ,three times/day)it will lift your eyelid a little to make it look normal, just be patient.
i wish you good health,
