These are the symptoms of a cold. The symptoms are likely to last a day or two and can be relieved by paracetamol
for your sore throat
. Drink plenty of fluid. Over-the-counter medications for nasal congestion
can ease your blocked nose. There are many available and the pharmacist can advise. This is likely to be caused by a virus, therefore antibiotics will not help. Rest if possible. A day off school may help speed up your recovery.
I hope you feel better soon,
