I can understand that the spray has caused an allergic reaction
in and around your eyes.
Since it has not come down with the creams for a week ,I think you are still in contact with the irritant.
1. Change all your pillow covers and the bedding sheets.
2. Try cold
water compresses for about 5-7 mins twice a day.
3.Continue your topical creams as suggested and a dose of oral antihistamines [for 2-3 days] should help you relieve itching.
4. Review with your ophthalmologist who can wash your eyes thoroughly by syringing and remove any remnants deep inside your eyes.
He can also guide you whether your swelling is due to allergy
or any other cause.
I hope this helps and have a speedy recovery :).
With appropriate treatment, [if it was due to allergy] you should be fine in 2-3 days.
