Daughter cough and sore throat for 3 weeks and getting worse

[Generallyok]

Dd is 8 and started with a sore throat 3 weeks ago which quicklily developed into a cough. At first it was just in the morning and was better in the day. The last 3 days she has been coughing constantly and has such a sore throat. I tried to make her appointment with GP yesterday but none available so saw practice nurse who checked her over. Said her chest was clear which I knew already as I can hear cough in her throat. Looked in her throat and said very sore but just viral. Surely a viral cough wouldn’t be getting worse after 3 weeks. Told me to keep her off school until better. She already missed a few days off school because of this virus before half term. What can I do to help her other than plenty of fluids.? She was crying in the night with discomfort. I’ve been getting her gargle with salt water regularly too. She has no fever.

Lozenges? Strong ones can help soothe the throat and ease the cough.

Could it be Hayfever? Might be worth trying an antihistamine?

When pollen is high I get a sore throat and a cough as part of my hayfever. Could that be it?

My son gets very bad hay fever but he always gets itchy eyes and sneezing too. A lot of my daughters class seemed to have had virus but didn’t hang around so long. I thnk it’s mucus running down the back her throat but she is too bunged up to blow. I have a humidifier running in her bedroom to try and help. Am I unreasonable to take her back to GP tomorrow. I can’t really send her to school as she coughing so much

My DH is just beginning to feel normal after having a cold for 3 weeks or so. He didn’t have a cough / sore throat but he was struggling with his sinuses and pressure in his ear. Seems wharever virus is going about is lingering for 3 weeks or so

And never unreasonable to get a 2nd opinion. Especially when it’s lingering for so long
