Hand, foot and mouth disease

Anyone know a good way to make my 3 year old more comfortable? She has the spots all down the back of her throat, her doctor gave us calpol and ibuprofen and a throat spray but shes scared of the spray. What sort of things could she eat that wont irritate her throat? Is there anything that can make the spots go away faster, especially on her hands (shes crying that they're sore when washing them after going to the toilet.) Hate seeing her so sick and uncomfortable. Thank you!

Edit-yes off course shes been to the doctor, he gave her a throat spray and said she can eat as normal after but her normal meals are irritating her throat even with the spray. When I asked if theres anything to soothe the spots he point blank said no but I was wondering if any other mums had any home remedies or a lotion that will calm the itch which wont sting her.
