Eyelid swelling lower/upper randomly. starts as hive on eyelid sometimes. i think i've connected it to ibuprofen, does this mean i'm allergic?

Possible: ibuprofen can cause swelling as well as hives. If you suspect it being the problem, you need to avoid it. Many feel that this type of reaction is truly allergic but there is no test to confirm the mechanism. Most can tolerate other types of NSAIDs without problem however and this is unlike NSAID induced asthma which would be triggered by any kind of NSAID other than Celebrex (celecoxib).
