Allergies are so frustrating aren't they? And sometimes there is no knowing what the allergen was, we can only make guesses. Yah, I don't even want to look at myself. Exactly! It takes days for the swell to subside. The longest I had experienced was a little more than a week. As the swell was subsiding, my eyes still looked as though I had cried the whole night or I had been punched. Luckily for this one, the dose was low and it took a few days to subside, not a week. The med had aspirin, and it is the prime suspect. No painkillers and aspirin for me moving forward.
