Eyes swollen closed - Hyper sensitivity

[Kaykaykaykay]

DD has this last week looked like she had done ten rounds in the boxing ring. Went on a bus and then flared up from nowhere. Any other parent experienced and found out root cause? Piriton sorted it out but scary for all.

If you’ve not already done so, an allergic reaction to that level and something possibly airborne or touch needs medical advice?

Spoke to GP and they said it could be anything!

Keep an eye and log any further incidents was advice though I am trying to find out what it could be/medical paths other people have taken...
