What would cause a hive to surface right below one eye??  Nothing else seems to be affected. Ive had pretty serious attacks the past couple of years where both eyes are so seriously affected that they swell.   Ive been diagnosed the past year with allergies to: dogs, corn pollen, ragweed, dust mites, and a chemical called thimerosal. Ive tried to be cautious of what Im coming in contact with and although, this attack isnt as bad as what it has been in the past, since Ive  tried being careful Im wondering if there is something else I should be doing.  It seems I am most often affected in August and December/January.
These are allergies as these allergies can't be avoided as they are in air you should go for immunotherapy as these are not fully avoidable and you can use anti-allergic tab ND ointment on the area for controlling it
