Otitis externa

Went to my gp the other day with earache was told I have swimmers ear was given otomize ear spray which just seems to sting my ear when i use them was just wondering if swimmers ear can cause a sore throat the same side as my swimmers ear is this normal? 

If it is an infection caused by Swimmers Ear,then it can travel into your throat,so yes you can get a sore throat. The ears,nose and throat are all connected.
