HI, thanks for using healthcare magic
During a course of a viral respiratory tract
illness, the inflammation that can occur in the respiratory tract can cause temporary bleeding.
This would resolve with the illness.
Though sore throat
is usually related to a viral infection,it is possible to have bacterial infection of the throat.
In which case antibiotics would be required.
If the pain persists or increases then you need to consult your doctor to rule out bacterial infection.
I hope this helps
