Sorry Osc I have just seen your post, so glad the little one is better.
My grandson had to be rushed to A@E last year terrible allergy caused by pollen Yasmin my daughter said the lower lids on his eyes turned inside out along with other frightening symptoms, she rang me two days ago saying he has had a reaction again this past few days. He is on medication again. Yasmin has to take anti histamine tablets every day. Chemical sprays contribute a lot to these allergies in Yasmin's case animal hairs hay fever.
Hope those who suffer with them young and old find the answer to this miserable often frightening condition.
